Hi bluesneedhelp,
I hope your boyfriend is going to feel better soon. If he has a good psychologist and taking medication he should be on the right track. I personally wouldn't contact his friends without making sure it's ok with him first..unless of course he is doing so bad that you are left no other choice but to reach out to his friends so they can help him. You are helping him by listening to him and being there and for now it's all you can do. I hope things get better very soon
