I found out recently my ex has BPD and recently had a manic episode. Her behaviour was taking a toll on all aspects of my life and I ended things as politely as I could because I realized she wasn't the girl I spent the last year dating. Now that I'm more educated on mental health I can't help but feel guilty for not recognizing the signs and helping her. She hasn't left the house in almost a week. She's had very little to no contact with friends or family. Her bestfriend actually reached out to me to see if I could get through to her. She's told me in the past about her depression and anxiety but I honestly couldn't tell until the last few months of our relationship. She was a casual drinker and drug user around me but has ramped up her alcohol and drug abuse the last couple months together and since we broke up. I feel like only have one chance to get this right l. What can I do to help her?
