I've been on one side or another of a lot of those problems, and though I can't offer any real advice seeing as I have yet to figure out how to cope with them myself, I can at least say to try not to give up. Even if everything goes wrong and it seems like you have nothing and nowhere to go, sometimes all it takes for things to get better is a little time. I know it probably sounds like I'm just spouting vapid nonsense, but it's what I tell myself when I feel like I have no hope. It doesn't help much, but every bit counts, right? I'm sorry I can't help more.
