It's my understand that they would have to admit you involuntarily for this (drugging you without your consent), and if you're not suicidal, they would probably not admit you (do not take this as TRUTH because this isn't a system I've worked in, but IME it's pretty hard to get admitted to a psych unit these days). I would be surprised if the first thing they did would be to drug you without your consent. What is your local ER? Cambridge Hospital? Could you call them and see what their protocol is for psych emergencies?

I'm sorry you're hurting, and I'll be thinking about you tonight.
