Letting go

It feels like there is something lodged in my throat like I'm short of breath. I can't breathe. I'm suffocating. I close my eyes at night and pray I'll be able to fall asleep. My eyelids shut but nothing else turns off. I lay there for hours, tossing and turning. I go from bed to couch, couch to floor, back to couch, just trying to get comfortable enough to maybe fall asleep for an hour. I'm exhausted.
I can't keep doing this. I can't live like this. I think I may be giving up.
