I can tell you that I had the same experience. I know for a fact that as I got older therapists just played games. I had 21 therapists tell me that they had nothing to offer someone like me who had been in therapy for so long. They give up on me cuz there is too much aging and not a lot of open doors for success - relationships, job opportunities - age discrimination, health starts going south. They want to work with young kids that have an entire life ahead of them. They find if they get a BPD really young they have much more success.
