My birth family knows of my suicidal thoughts and that I almost did it. They also know I see a therapist. But I did not tell them about my bpd. I have only told my best friend. And I only told her because she was the one I told when I was going to end my life. She was there for me and helped me make it through. But she was getting overwhelmed by my suicidal thoughts so I thought I should tell her so she could understand why i am the way I am. Told her to do some reading about bpd so she could see where I am coming from. She is still my best friend and very supportive of me.
