CBT can make you worse. However with the right perspective it might help. I'd suggest reading an ACT self-help workbook like "Get Out of Your Mind & Into Your Life" or "Living Beyond Your Pain" before, during and after the CBT courses. CBT teaches you that some thoughts, feelings, memories, etc. are irrational. That's fine, but then CBT says challenge and change those thoughts, feelings, etc into rational ones. ACT teaches us instead to thank our minds for it's input (however irrational it is) and do what we want to do based on our values. Until I learned about ACT I kept getting worse and worse. CBT made me worse because I spent all my time challenging irrational thoughts and feelings instead of actually living. With ACT we practice mindfulness, staying in the present moment. Instead of focusing on what's going on inside us we focus on what's going on around us. We can't control our thoughts, feelings, etc. but we can gain control of our arms, legs and mouth.
