Just wanted to say I'm sorry you're feeling this way and I can definitely relate, to a lot of your posts actually. I don't really have any in real life friends, or at least none that super care about me. The three I do have are always busy or away. My family gets on my nerves at times as well.
I've been making more changes this year and as a result my mood has become a lot better overall, but I definitely understand the stress part.
For what it's worth, I do appreciate you and seeing your posts around here. Especially in the basement. You're a very funny, reasonable, and thoughtful person, and I'd hate to see you leave here if you did, but would also understand.
I do hope that things get better for you soon. Just don't give up.
