Brother may have a mental problem...please assist

[scotchnrocks]

I was pretty sure about the bipolar thing, but didn't want to mention it in order to not influence replies. I've also been researching schizophrenia because of the crying.

I guess what I'm really asking here is how to best get him to the help. My parents mentioned talking to someone and he blew up at them. He has told them he will not talk to them for a month now but will probably stop by tomorrow and act as if nothing has happened.

I asked my mom about mental disorders in our family and she said she was depressed for a little while but nothing else from any other members. My great-grandma is almost 100 and still gets around w/o assistance.
