Sorry you're struggling so much

Do you have a doctor or therapist you can get in touch with? 5 nights is a long time without sleep. I would recommend reaching out to some kind of professional, even if it's your GP.

Have you tried something like Ambien, Remeron, Seroquel, etc yet to help knock you out? Heck, sometimes even Klonopin is good enough to calm me down when I'm all revved up.
