I don't think the "breaking" is necessary to get better. I've done the meditation and the DBT and have gotten enough out of it to make things easier. The hard part is to stick with it. On the days you feel good, you don't do it. You get that feeling that "all is better now"; you deceive yourself, and that make it harder when you're having a hard time and try to get back in to it. I don't think there's a "cure", but there are things you can do, with or without therapy, to help.

Let me know if you'd like info on the meditation and DBT I've tried. I'd be happy to pass on the info.
