Some of us are here to help others as a way of working though our own problems, and I'm quite certain I'm not the only one. You're being here, and however depressing your posts might be (or not), that's likely helping others not just yourself. I'd likely not be here if everyone was happy and had found their way. Its a community, we all add to it, we all fit somewhere.
Personally I'm a bit lost, but I've mostly managed to accept it. I am what I am, just not really sure what that is sometimes, and that's fine. Give it time. Lots and lots of time.
