<human>: Hi Reddit,

Throwaway for anonymity.

My friend hasn't spoken to me for a few days, while we used to talk every single day. He's been disowned by his parents, for reasons I won't state here, and the way he handles trauma is very much "I'm on my own" and he tends to pull back from those who care about him.

He is susceptible to being cared for, but one has to be extremely confident and sure about what they're doing, or it'll be worse and he'll get more upset, more hurt. We've been through more situations where he was hurt and I've heard him tell stories about him doing the same with other friends. It's the way he is.

Thing is, I'm not a confident person. I have some issues with my mental health. I'm in the process of being diagnosed right now, and there are indicators of Asperger's, some other minor issues, and/or a possible identity/personality disorder. I'm not good at being there for other people and I'm typical with having to be told exactly what to do when doing things, if I'm not certain I sort of shut down.

I want to be there for him, but I don't know how to. It doesn't help that the relationship I have with this guy is very complicated. We've known each other for about a year now, and our relationship has gone from great and partly romantic, to less so, to bad, to horrific, to being salvaged. Currently we're still on the latter. It's mostly gotten so bad because of my issues with being there for others.

Now since we've already been through so much he has told me to just lay off - I'm prone to seeking attention, this post being another example - but I don't want to just leave a friend standing out in the cold. He has others who are presumably standing by him but I don't know that for sure. 

Should I just lay off and wait for him to be ready for me again? Or should I figure out how to help him, and how do I go about doing that?

Provide a brief overview of the text.
