He is, and I'm pretty sure it'll pay off if he sticks with it. That's a big 'if' though.
Trouble is that he would never have sought any assistance had he not more-or-less wrecked the fragile world he'd built around himself, so there doesn't seem to be much incentive to try and turn things around. And when I say he's difficult to love, I mean really difficult. Impossible for most people to relate to, and on occasion pretty twisted and hateful. Sometimes it's real, sometimes a put-on, sometimes a mixture of both. It's all pretty understandable when you get to know him, but he's wary of people to the point where he pushes them away, plays headgames and shit. Even I have to stop myself from punching him sometimes. There's a weird kind of purity and honesty to it all though, and you know exactly where you are with him at all times. Which is pretty rare, all told.
There's an awful lot of emotional wreckage to untangle, and it doesn't really help that he can't even seem to take his own feelings seriously. Seems to hate himself while making it appear the exact opposite. Denies being depressed while being the most depressed person I have ever met. And sometimes a grinning, manic, destuctive, demonic idiot. A total fuck-up from head to toe, basically. :D
I don't know; there's only so much you can do with a person like that before they start to eat you up. The kind of unconditional support he needs is so demanding that it burns people out, and it's not as if it's rewarding in any way other than being a part of this charming, witty, charismatic, loving but also stone-crazy guy's protracted death trip. And he has a gift for sabotaging any close relationship anyhow.
Sad to watch, but what can you do without jumping in the fire yourself?
