I think there's a lot of chance he is bipolar, although, it;s entirely up to _HIM_ to do something about it all the love in the world won't allow him to see he needs help.....especially if your mother and your best friend are also convinced something has to be wrong with him...medication can help, that's if and when he agrees to see a doctor.......sometimes someone acts out so badly they are sent to psychiatric emergency or someone has a run in with the law and then they get help let's hope it doesn't come to this, though...I feel for you, anners, and see how deep your love is for your boyfriend, you must feel powerless.....does he have any friends that also see this? What does his family say? I noticed you wrote that he was diagnosed with depression as a teen, whatever it took to get him to see a doctor at that point, perhaps under the same circumstance he will see the same doctor again..you have found a very supportive community here and I hope you continue to post here, I care about you.........
