Do you have a psychiatrist? If so I would call them and tell them what's going on, they may be able to call something in for you. If not, I would go to the ER and tell them you can't sleep, it's very important because the longer you don't sleep the bigger chance you may end up getting psychotic symptoms at some point and it's just not healthy at all in general. I'm sorry you're going through this. I hope you can get some sleep soon

EDIT: If you end up going to the ER, have someone else drive you
