What can I do?

I think he thinks im using him for a good laugh... if only he knew. I see him get depressed, and when everyone else would get fed up with him I don't. I see that he is suffering and I try to help him. Introduce him to my friends, try to get him to do something like work out(he says it wont matter) but it will you all would agree. If you get a nice body women will notice. I tell him to join something, like work out now and join wrestling so he can meet people. All he does is sit around felling like shit, and then trying to make people pitty him(sadly I do). He says there are things wrong with him and uses that as a reason. I tell him, you can use that as an excuse, everyone has things wrong with them and they just deal with it. I know why he uses the excuse, its so when something goes wrong, he can just blame it on that and make himself feel better, truely understandable but not the right thing.

Its my turn to ask "what can I do" to get him to see how it really is and that I am trying to help.
