I am 18 yrs. old and have major trouble trying to fall asleep. I've been this way ever since i can remember. I am almost certain it's caused from anxiety because my mind is constantly racing and i constantly feel like I'm going to miss out on something. If i have to make a big decision (depending on how long I think about it) I increasingly become panicky. I have gotten xanax a few times from people i know that have it and it seems to help a lot.
