I have not been properly diagnosed with BPD, I have been diagnosed as suffering PTSD Depression &amp;  Bi polar II disorder. 

So one day I was reading a Quora post on a BPD page I had joined because I thought it was abbreviation for Bipolar Disorder, but this woman's post and testimony of her life and feelings and thoughts and emotions resonated so much with me that I am almost certain that I have BPD. Her post resonated with me more than Bipolar II ever has. Now I know I shouldn't go off one person's post but it was so on target. 

Can anyone give me more information and perhaps how did you find out that this was something you "had" ?
