Good for you. People like them are losers to begin with, they aren't happy so they try to drag others down with them, particularly those that are different from the norm since they see them as easy victims, and they'll say things or do things just to make you feel bad about yourself. Try to continue to not let it bother you so much, just focus ahead on your goals, those near and easy to reach as well as those a long ways off still, you'll get somewhere, they most likely will still be where they are.
