So, with my therapist’s guidance, I was able to do my own after she picked out things I specifically needed to work on. I ordered a DBT spiral workbook and learned from there, I can now apply these skills daily. It’s saved my relationships and life. And yes, you have to re-wire basically your entire brain and world view. I was able to get it done in about a year.
Yes. Mine changed because I changed it. I had BPD my entire life. My providers are certain I was born with it. I’ve always only ever known extremes and unstable relationships, until now- after a year of intense DBT treatment. I have changed my personality, my entire perspective on life, so yes. I hope the OP sees this. (I’m also bragging a bit, it only took a year to recover from a disorder I unknowingly had my entire life once diagnosed and was informed.) You have to rewire your entire fucking brain, but you can.
