I wish to point out that doing DBT/CBT is a lifestyle. Yes, I am serious about this. Although it's now been months since I completed a program, I continue to do the work. I do exercises weekly and as-needed.

That de-catastrophizing thing has been a life saver. My catasrophic thinking had rendered me terrified to do anything but helped me find the strength to cope.

For example driving. I was terrified I'd have car trouble, not be able to park, and even tick someone off (the list continues). But it is likely I realized these things would not happen. Still, I went back over these things and considered what to do if they did. If the car broke down I'd call my brother, I would drive another block if I had to find a spot I would be comfortable in, if someone got angry that was their problem, etc.
