From what you've told us, I am not optimistic of your chances.
(a) You have told us that you're a convicted drug dealer, which normally would mean that your chance of legally reentering the U.S. hovers at roughly 0%.
(b) You cannot jump back into LPR status - you would have to start the entire process from the beginning. You can discuss with your mother the possibility of her sponsoring you as an unmarried child over the age of 21 (assuming you're unmarried), but that preference category has a very long wait.
