I think even though it took a very long time 9 years total psychodynamic and reparenting. Then I attended DBT but I had the ground under me and more ego strength. I was a lot older when I was dx with BPD. So age was also a factor. Until the end I had a really good T. He fired me. UGH!!! Because I was regressing instead of getting better and he pull the plug UGH. I went to 2 different DBT T one had been trained by Marsha herself. I was lucky with that.
