This is my first post.
I believe my brother may be bipolar. He has periods of extreme high's where he can't be reasoned with, then he will lock himself away from everyone for weeks on end. He has never been diagnosed as bipolar but he has recently been treated for depression and anxiety. He has had these issues for as long as I can remember, so it's not a recent thing. What can I do to help him get the help he needs? Who can I turn to? His GP obviously can't discuss things with me, so I have written her a letter detailing all I have witnessed through the years and giving a little insight to his past. Is there anything else I can do?
