Hey Sweetie............you are most definitely NOT dying, but you need to let your parents know how scared you are so they can help you. Your symptoms are all very common for anxiety and depression and not a single one of them can harm you in any way.
Please talk to your parents or call the doctor who perscribed these meds for you and ask him/her to give you the reassurance they should have given you before you left their office!
Sometimes when we up our dose, we get a little nutty again, but it doesn't last very long and you sound like an intelligent and strong young person, you'll get through it!
I think it would be really helpful for you to talk to a therapist who deals with young people...........the meds will help with your symptoms, but they won't cure what is causing them. Can you talk to your folks about checking into some therapy or possibly a counselor at school?
These issues are often difficult for adults to deal with alone, at 14 you should have someone you love and trust to lean on.
Write to us anytime you feel alone, OK? We have lots of young people on this forum.
Take care Kristen!
Peace
