What is Cognitive Behavioral Therapy (CBT)?
Cognitive Behavioral Therapy (CBT): Learning Not to Believe Everything You Think
Cognitive Behavioral Therapy (CBT) is often considered the gold standard for treating anxiety and depression. Decades of research show that CBT can help people feel less overwhelmed, function better day-to-day, and improve overall quality of life. It is also effective for stress, sleep difficulties, relationship concerns, and adjusting to life changes.
CBT isn’t about forcing yourself to “think positive.”
It’s about learning to see your thoughts more clearly,
so you can relate to them differently and respond with greater choice.
The Core Idea Behind CBT
CBT is built on a simple, research-supported understanding:
What we think and what we do shape how we feel.
When anxiety or depression shows up, our minds often fall into unhelpful thought processes without us realizing it. These thoughts can sound convincing:
- I can’t handle this.
- Something bad is going to happen.
- I’m letting everyone down.
- I should feel better by now.
Over time, these thoughts can influence behavior, like avoiding situations, withdrawing from others, overthinking decisions, or constantly seeking reassurance, which can unintentionally keep anxiety and low mood going.
CBT helps you step out of that cycle by learning to notice thoughts, look at the evidence, and respond in new ways.
Identify, Challenge, Change
1. Identify unhelpful thought processes
The first step is learning to notice what your mind is telling you in stressful or low moments. Many of these thoughts are what CBT calls cognitive distortions, mental filters that can color how we interpret situations. They often feel true in the moment, yet may not be fully accurate or helpful.
As I often tell clients:
When experiencing anxiety or depression our minds can work as a filter, only letting thoughts that fit the narrative through.
So remember:
Don’t believe everything you think.
Our minds can mislead us sometimes.
Just because a thought appears doesn’t mean it’s a fact.
2. Challenge the thought with compassion
CBT views thoughts as ideas to be explored, not truths to obey. Together we slow things down and ask:
“Let’s look at the evidence for or against that thought.”
We might also consider:
- Is this thought based on fact or assumptions?
- Is there another way to understand this situation?
- What would I say to someone I care about in the same position?
- Am I predicting the future without real prof?
3. Change patterns in real life
CBT places equal importance on behavior. Through behavioral intervention and behavioral activation, we make small, realistic changes that give your brain new information, like gradually approaching what you’ve been avoiding or rebuilding routines that support mood and energy.
Over time, these steps help anxiety settle, mood lift, and confidence grow in a way that thinking alone cannot accomplish.
What CBT Can Help With
CBT is especially helpful for adults who notice:
- Worry that spirals or feels hard to control
- Feeling on edge, tense, or exhausted by anxious thoughts
- Low mood, loss of motivation, or feeling “stuck”
- Avoiding things that used to feel manageable
- Feeling disconnected from yourself or others
The goal isn’t to erase difficult thoughts, it’s to change your relationship with them so they no longer run the show.
CBT can also be thoughtfully combined with medical care for health-related anxiety, helping you cope with real physical symptoms while reducing the fear and uncertainty that often amplify them.
