You can do anything you want to do. I left school after my freshman year back in 2001. I started and stopped at community college and online schools. After a bunch of chaos in my life, I finally made the decision to go back because I was stable on medication. I graduated in December of 2012 by a combination of online classes and on campus classes. As long as you're committed to it, it is absolutely possible. Stability on your meds is important though because it can get stressful at times.
