Hi Screenager. I'm sorry you are having such a tough time. Have you seen a psychiast? I'm sure you are aware there are medications to help syptoms like yours. I used to have panic attacks, I'm on medication for it now. Also, was in group that did deep breathing technique, which really helped.

Just them that you are taking a break to decide what direction want take. If they ask any thing else just tell them you are sure right now.

Or if you don't want to go tell you are sick and can't make. That would not be a lie because you are making yourself sick worring about it.

I know just you feel about sleep, I sleep about 10 hours a night to be able to meet the day.
