You are very impulsive but with your recent drug usage I’d be reluctant to say any diagnosis. There’s a very fine hard to distinguish line between bpd and cptsd. But DBT works for both. And anyway I’m not a professional so my guesses are just that, guesses. Just from drug users I’ve known in life the longer they are clean the more stable and less diagnosis they have. Some of them have told me that they stopped maturing when they started using and didn’t grow up until they stopped using and that their previous diagnosis was just immaturity. So who’s to say?
