Since I became stressed out just reading your question, I can only imagine how stressed out YOU are. Please just slow down for a moment and try to relax. You can’t do everything at once, and you can’t correct past mistakes overnight. I suggest a heart to heart talk with your mother about the whole problem. Just tell her you don’t want to disappoint her, but you don’t know how to get your life on the right track, and you need her advice. Failing that, find a school counselor whom you trust and ask his/her advice. Above all, right now, try to stay calm and stop stressing yourself out about things you can’t control. Remember to ask for help from everyone around you. Don’t continue to carry this burden all by yourself.
