I really hope you feel better as soon as possible.

It's horrible to feel like crap in a house other then your own. I completely understand that. I also totally understand not wanting "cute little messages" from a significant other when in a state like this. Sometimes it really doesn't help and can be overloading. I guess just try and see it as that people care for you (Easier said then done, right?).
I agree with Smmath, writing in a journal can help. Plus if you spill your heart in writing and burn it that can be pretty satisfying. I also find night air can help a little, maybe try opening a window and sitting next to it?. I find the more simple coping skills are the more you're able to do them when you're in a bad state.
Seriously, if you need a one on one talk feel free to message me. I know we don't know each other that well. But just know I'm here. Plus you seem like a really nice person. If not, it's okay. Either way I look forward to possibility getting to know you better.
You're in my thoughts.
