Signs that therapy is working include gaining new insights about yourself and your patterns, developing better coping skills, feeling more self-aware, and seeing gradual improvements in the areas you wanted to address. You might notice you're handling stress better, communicating more effectively, or feeling less overwhelmed by emotions. Progress in therapy isn't always linear - you might have setbacks or feel worse before feeling better as you work through difficult issues.
If you're not seeing any progress after several months, discuss this with your therapist. Sometimes it's about finding the right approach or therapist for you.
