I diagnosed myself at the age of 49 after seeing 16 therapists starting at the age of 17. Last year I was dating someone strange, spent every waking hour online researching to figure out what was wrong with him, discovered he had Narcissistic Personality Disorder and through all the reading found out I was Borderline. No one through all those years could figure it out.
I wasn't completely honest with each therapist about my thoughts and feelings but I don't think it was entirely my fault. I truly didn't know how to put it into words. How could you desperately need love and simultaneously push it away? That sounded strange and to hear myself say it out loud, well it scared me. The day I discovered what I had, the guilt went away. All those years of feeling like a freak finally made sense. It wasn't my fault!! The earth was lifted off my shoulders.
Anyway, just curious how others found out about their condition.
