I don't know how much longer I'll be able to cope with this up and down and thrashing about. I'm getting nauseous and ready to throw up.

In 5 seconds I can go from hysterical laughter to wanting to die, then stay that way for a solid 10 minutes, then get angry, then laugh it off, etc.

I know this is a combo of not sleeping and substance use. But the not sleeping caused the emotions caused the substance use caused the emotions and the not sleeping causing the emotions causing more substance use............
