One thought - not sure if this is an option - but some mental health facilities have an outpatient day program that you still come home at night. But it's intense like a hospital stay. Is there something like this in your area that you could try? Maybe get the intense help that you need...but still be able to take a break and go to your graduation, and the shower, etc. Just a thought.

I've never actually been in one of these programs, I just remember reading about them.
