Acceptance and Commitment Therapy (ACT) · Chicago, IL

What if the goal was not to eliminate your pain, but to stop letting it run your life?

Acceptance and Commitment Therapy is a mindfulness-based approach rooted in the understanding that painful thoughts and feelings are a normal, inevitable part of being human — and that the struggle to get rid of them is often what causes the most suffering.

I use ACT as a core part of my work with teens and adults in Chicago, Illinois, particularly for anxiety, depression, OCD, relationship issues, and life transitions.

What Is Acceptance and Commitment Therapy?

You are not your thoughts. ACT helps you live that truth.

ACT stands for Acceptance and Commitment Therapy. Its foundation is built on two core ideas that work together: we cannot eliminate painful internal experiences, and we can learn to stop letting them determine how we live. Rather than working to change the content of difficult thoughts, ACT works to change your relationship with them. Thoughts are understood in ACT as mental events — not facts, not commands, and not definitions of who you are.

You are the person who experiences your thoughts. You are not your thoughts. That distinction, while it can sound philosophical, is genuinely transformative in practice. When you can step back and observe a thought without automatically believing it or acting from it, its grip on your behavior changes in a way that feels like a real shift in freedom.

ACT also places enormous emphasis on values. Rather than asking what you are feeling or what you should stop feeling, ACT asks what matters to you and how you can move toward that, even when discomfort is present.

The ACT bus metaphor: Right now, your thoughts and feelings might be driving the bus. ACT helps you get back in the driver's seat. Your thoughts become passengers. They can make noise and try to tell you where to go, but you are the one who decides the direction. Your thoughts are not you.

The Core Concepts of ACT

Six interlocking skills that build psychological flexibility

ACT is not just about accepting discomfort. It is about building the full range of skills needed to live a values-driven life even when pain is present:

Cognitive Defusion

Learning to observe thoughts from a distance rather than being fused with them. Instead of being trapped inside "I am not good enough," you learn to notice "I am having the thought that I am not good enough."

Acceptance

Making room for difficult thoughts, feelings, and sensations without fighting them or trying to escape them. Not resignation, not approval, but choosing not to spend energy on a struggle that cannot be won.

Present Moment Awareness

Developing the ability to engage with what is actually happening now rather than being pulled into rumination about the past or worry about the future. Mindfulness practices are a key tool here.

Values Clarification

Identifying what genuinely matters to you at a deep level, separate from fear, expectation, or what others want from you. Values become the compass that guides the committed action that follows.

Committed Action

Taking meaningful steps toward a value-aligned life even when anxiety, fear, or discomfort is present. The goal is not to feel comfortable first and then act. It is to act in alignment with your values regardless of how you feel.

The Observing Self

Learning to relate to yourself as the one who experiences thoughts and feelings rather than being defined by them. You are the context in which these experiences happen, not the experiences themselves.

How ACT Differs From CBT

Two evidence-based approaches that work differently

Both CBT and ACT are evidence-based and effective, and I frequently use both in my work with clients in Chicago. The key difference is in how each approach relates to unhelpful or painful thoughts.

CBT focuses on challenging and changing distorted or inaccurate thoughts: examining the evidence, evaluating the logic, reframing the interpretation. ACT does not evaluate thoughts for accuracy at all. It teaches you to step back, observe thoughts without judgment, and let them come and go without attaching meaning or acting from them.

Sometimes cognitive reframing is genuinely helpful. Other times, the thought is too deeply rooted or the situation too ambiguous for reframing to work. In those cases, the ability to simply observe thoughts without being ruled by them is what actually produces change.

What ACT Is Especially Helpful For

  • Anxiety — observing anxious thoughts without fighting them, moving toward what matters even when anxiety is present
  • Depression — getting unstuck from patterns preventing meaningful engagement with life
  • OCD — used in combination with ERP to recognize intrusive thoughts as mental events rather than signals
  • Relationship issues — not internalizing negative beliefs and identifying what you genuinely value in connection
  • Life transitions — staying connected to values when everything around you is uncertain
  • Perfectionism and self-criticism — building psychological flexibility to move forward without requiring everything to be resolved first

ACT is especially valuable for people who have tried other approaches without lasting results.

ACT Exercises I Use in Sessions

Concrete, practiced techniques that create real change

Leaves on a Stream

Imagining thoughts as leaves floating down a stream, allowing them to come and go without reaching in to grab any of them or trying to push them away. The goal is observation without engagement.

Labeling Thoughts

"I am having the thought that..." Rather than accepting a thought as fact, labeling it creates cognitive distance and reduces its automatic power over behavior.

The Values Arrow

Drawing an arrow representing the life you want to live, then examining whether your current thoughts and behaviors are moving you toward that direction or away from it.

Visualizing the Observing Self

Guided practice to access the part of you that can notice thoughts and feelings from a step back, without being swept away by them.

Values Exploration

Structured conversations and exercises to identify what genuinely matters to you at a deep level, separate from what you have been told should matter.

Committed Action Steps

Small, concrete actions aligned with your values that you take between sessions — even when discomfort is present. Action comes first; waiting for comfort to arrive is not the goal.

Frequently Asked Questions

ACT therapy questions, answered

What is Acceptance and Commitment Therapy and how is it different from other approaches?

Acceptance and Commitment Therapy is a mindfulness-based, evidence-supported approach that focuses on changing your relationship with difficult thoughts and feelings rather than trying to eliminate them. Unlike CBT, which works to examine and reframe inaccurate thoughts, ACT teaches you to observe thoughts without judgment and without letting them drive your behavior, regardless of whether the thoughts are accurate. Unlike traditional talk therapy, ACT is action-oriented and values-focused: the question is not only what you are feeling but what matters to you and how you can move toward that even when discomfort is present. What makes ACT particularly distinctive is its emphasis on psychological flexibility — the ability to hold difficult internal experiences with openness while still moving meaningfully toward the life you want.

How does ACT help with anxiety specifically?

ACT is particularly well-suited to anxiety because it addresses something that other approaches sometimes miss: the struggle against anxiety often intensifies it rather than reducing it. When we treat anxiety as an emergency to be eliminated, we paradoxically give it more power. ACT teaches a fundamentally different relationship: making room for anxious thoughts and feelings without fighting them, observing them without attaching meaning, and choosing to move toward the life you want anyway rather than waiting for the anxiety to go away first. Over time, this changes the relationship with anxiety in a way that allows for genuine freedom rather than just temporary relief.

Can ACT help with depression?

Yes, and ACT has a particularly important and distinctive contribution to make in the treatment of depression. One of the defining features of depression is getting stuck — unable to take meaningful action because the emotional weight feels too heavy, waiting to feel better before engaging with life again. This waiting often deepens the depression rather than resolving it. ACT addresses this directly by helping people identify what actually matters to them and take small, value-aligned steps even in the presence of depression, rather than waiting for the depression to lift first. ACT for depression is not about forcing positivity or pretending to feel differently than you do. It is about reconnecting with meaning and action even when everything feels flat, heavy, or meaningless.

Is ACT appropriate for teenagers?

Yes. I use ACT regularly with adolescents in my Chicago practice and find it genuinely effective when adapted appropriately for their developmental stage. The core ACT ideas resonate with teenagers once they are framed in language that connects to their actual experience. The idea that thoughts are not facts, that struggling against pain often makes it worse, and that you can take meaningful steps toward what you care about even when you feel anxious, sad, or uncertain — these ideas make intuitive sense to most teenagers. The bus metaphor, for example, tends to land particularly well with teens.

How is ACT used alongside ERP for OCD?

ACT and ERP are a natural and powerful combination for OCD treatment because they address complementary dimensions of the problem. ERP addresses the behavioral component by helping you face feared situations and resist compulsive responses, allowing the anxiety to decrease naturally over time as the brain learns that the compulsion was not necessary. ACT addresses the cognitive and psychological flexibility component by helping you observe intrusive thoughts without judgment and without treating them as meaningful signals that require a response. Together, they change both the behavior and the relationship with the thoughts that drive it. When I work with OCD clients in Chicago, I typically integrate both approaches because each one covers ground that the other alone does not fully address.
