Do I have any chance of play D1,D2, or overseas basketball?

Averaging 22 points junior year means you definitely can get into a D2 school, if not a D1. If you need to get back to the fundamentals, a personal trainer/coach will give you everything you need. As long as you didn't fail all of your classes, you should have no problems with getting to a good school, and emailing coaches with videos of you playing along with your stats will pretty much guarantee you a place on a good team.
