Hi confused,
Yes, there are lots of great books out there on DBT. There are workbooks as well that I think would be really beneficial to you. There are DBT websites as well.

Yes, you can be a recovered borderline. I would be happy to assist you in DBT skills practice. The skills really work. Some of it sounds really stupid to start with, but if you really give it a sound try, it can help you out.

Please feel free to PM anytime if you want specific titles, authors, etc.

Welcome to PC!!
Hugs,
Okie
