This is my experience. The best friend I've ever had was a man named Jim who stuck by me through two decades. The relationship is over and he won't answer an email and it's all my fault.

I also suffer from depression and for a few years, the depression got worse and worse. During this time I became an angry, needy person who became very difficult to be around. For years Jim had gone every weekend halfway across the country to see a women he was involved with. Of course I didn't want him to see her and mostly I just accepted it, although sometimes I'd say something catty about her.
As my depression got worse, I did too. Jim decided to move to live with his girlfriend and at the end, we had a huge fight. He never spoke to me again.

After he left my wonderful psychiatrist found the perfect cocktail that restored me to sanity. I literally woke up one morning another person. I viewed the world differently, if I felt anger I no longer had a need to express it.

But it was too late and what I learned is that I'm always responsible for what I say and do. I don't blame him for reaching the point that he couldn't stand it any longer.
I didn't know about bpd. If I had I would have sat down and gone over my reactions. And knowing I had this problem, I could have chosen to respond differently.

We may have a disease but we're also responsible for getting treatment for it as a way of handling it. I ended up alone and miserable because I didn't know what was wrong. I hope you don't too.
