Feeling better

Here are some other suggestions:

Talk about it

One of the best things you can do for yourself is to talk.  Talking about your feelings—not just once, but often—almost always makes you feel better.  It releases tension, and can help you put things into perspective, so they don't feel so overwhelming.

So:
Tell your parents how you feel.  If they are too upset to be helpful, try again another time.  Talk to someone else in the meantime.

If you have brothers or sisters, talk to them.  Since they're going through the same thing you are, they'll probably understand how you are feeling.
