Berries, sending so many hugs. I'm sorry you're feeling like this. Please consider what you might need to take care of yourself - if you need to be admitted to make sure you're ok please do it.
You're having a rough time. Please try to stay awake. Escaping thoughts is not the answer. Maybe right now you need a break, but overmedicating is dangerous, please don't do it that way.
do you have a professional you can call? At the very least they can give you sleep meds?
