I can sense a lot of embarrassment in your posts and while it's an understandable emotion, it can be very paralyzing. So try not to dwell on the thoughts of your mother or others very much. It hurts your growth more than you think. I think you should just accept your predicament, and make your next move.
Also, don't feel like you burned a bridge down by withdrawing from college. You can always re-enter college (if you later feel that your career aspirations require it), even if you were in bad-standing. Undergraduate colleges will usually let you back in multiple times because unlike professional school, there is always room for students. And plus, they love making $400/class (+ "maintenance costs"). I know, because I've done it before.
