To stay in school, you may have to swollow your pride big time and volunteer to do some kind of rehab.
You have to be upfront about what has happened.
Don't even try to go the route of "I was holding it for somebody" "it's not mine" etc....etc....

It's really up to you how important your education is.

You can be well off in a nice house, able to vacation one day OR you can end up in a rooming house scraping up enough $$ for oodles of noodles.

your choice.
