What can i do to help? Please read!?

If you had not heard your brother and mom talking would you still want to reach out to him? Sounds like you feel sorry for him and a little guilty on top of it. He has enough problems don't add guilt to it.

I'd introduce myself to him the next time your brother has him over. I'd kindly mention the fact that you've seen him round your brother, and never thought to introduce yourself. If you get a nice, balanced, and solidly decent base connection with him, he might start talking to you, and you two may have more in common than you might think, and then HE just might reach out to YOU. And if that time comes, I'm sure you'll know what you can or should do, but I would at least introduce yourselves and get on good terms. I wouldn't let on that you know these intimate details of his life; I'd wait until he tells you, that is, if he decides to tell you. But addressing these details to him, and he may get scared and back off, and you may not see the rest of the story.

I hope this helps. I know how frustrating knowing something about someone like this is.

well, the problem is when you get a friend with drama you may cause yourself drama! knowing that, if you still want to talk to him you have perfect oppertunity cuz hes friends with your bro. just take a minute to ask him how hes doing. dont look too concerned like u kno something just try to be subtle. the only problem is you will be coming out of nowhere so he might end up thinking you are romantically interested!

I had a similar situation.Just started off with small talk..get the conversation going until he feels comfortable enough to confide..then hook him up with some of your knowledge! you may save his life so its worth a try.

Support your brother .Encourage him to get involved .That's a good place to start .

talk with your brother and give him some wise advice it could help him
