Why does my anxiety make me feel so bad sometimes the thing that scares me the most is when the feeling makes me jump back in my seat like im falling?

This can happen.: It's good when you start to feel anxious to quickly take deep breaths and try to relax. You might consider learning to meditate or to take up yoga. These are great to make you feel more relaxed in general and shoud decrease your anxious episodes..

Emergency Reaction: The purpose of the anxiety response is to assure survival. It is your emergency alert system. Unfortunately, some people have it go off for no reason (a little like epilepsy -- just neurons firing). That's when it gets in the way. Try cognitive behavioral therapy, good sleep hygiene, avoiding caffeine, nicotine, & other substances. Regular exercise & meditation are also very useful.
