Angie,
I know how you feel! I'm taking a college course right now on campus and its 3 hours! I get there which is a good step and feel dizzy and can't concentrate just because i'm thinking 'oh boy i've gotta sit here for 3 hours can i do it and not make a fool of myself!' I too feel like i cant sit still and ugh its so annoying! I know exactly how you feel your not alone!
