I care if you wake up tomorrow so don't over do it with the pills. Call your doc now or go to the hospital and let them put you to sleep safely. It can be done.
If they aren't helpful, get pushy and make them give you what they need. If you tell them you're prepared to take as many pills as it takes to not be awake anymore they will listen. And it sound like you're at that place I've been where you would do anything to just not have to be awake anymore.
Let the pros put you to sleep and when you wake up, you will have done something. You will have slept. Trust me on this, mixing all the sleeping pills and taking the mega doses is not going to get you any more sleep or better quality sleep. It's just going to make you dazed and confused and puking your guts up (if you're lucky).
Go find a doctor to put you to sleep now. Immediately. Just do it. And come back and let me know when you are awake. I need another insomniac around here to keep me company. Of course, I'm happy to entertain myself if you're finally able to get some sleep. Just send the sleepy vibes along for the rest of us. Here we go chasing you to the doc
