I did learn useful things in DBT. I just don't really put it into practice. I automatically turn to my negative coping skills and don't really even think of the positive ones. Honestly, I should go through DBT again, maybe.Psychologists and Social Workers seem to be the best at recognizing Borderline Personality disorder. Medical Doctors seem to be looking for something else that they can easily treat with medications. ( When all they've got is a hammer.... everything looks like a nail... )
It's interesting that DBT wasn't effective; I haven't tried that but it has been recommended to me many times.
I can relate to the pain you are describing, though. Yes, the pain is too much to bear. I feel like that often, daily to be honest. And this time of year is hardest for me... and the fall. It's how I was conditioned.
Yes, the end of the year is always hardest for me. Everything hits me at once - my loneliness, missing my mother, the holidays, etc.
