hey, justdon'task, it sounds to me like you may be depressed. can you see a school counselor to discuss what is going on? i am concerned that you do not want your parents to know that you are having feelings and seem to be losing interest in your life. why is that? did you get great grades in order to be the perfect child for your parents? are your parents divorced or separated (from the way they share expenses, it appears they might be)?

it seems that you may have been living for them rather than for yourself. however, as you get older, living life for yourself starts taking over and, when it comes to your life, you don't seem to see is as being as important. of course, your life is most important - more important than your parents and more important than being the perfect child. please talk to a school counselor about your feelings and do not feel guilty if your parents are called in. your parents are supposed to be there for you. it's their job. they are supposed to help you grow up and be there for you emotionally. it's not your job to be perfect and to hide your feelings and other parts of you that you feel may not be perfect from them in order to protect them.

YOU are the most important person here and you, right now, need a little emotional support that you can't provide for yourself. Please see a school counselor right away.
