Hey, I'm really glad you wrote here.
I can relate to about everything you said, and I know this doesn't help much, but I'm here for you, always. Just a kind ear, if you need, you're not a burden or any type of disappointment. You're awesome, and I know you don't believe it, but I'm going to keep telling you.
The first step though, might to just to get out of your room for ten-twenty minutes, and if you still feel uncomfortable, go back. But keep trying to get out.
Hang in there, and Take Care.
