Hey amigo!
This saying used to be popular (I'm not sure if its part of the lingo these days)... "life is the pits"....
I'm sorry you're down in the pits... I don't think you're alone... its a really busy time of life for you... pat yourself on the back that you've managed to accomplish all that you do each day! School is a horribly stressful time.
Its great that you've checked in here... you know how much we all care

and although we're not all here all the time... our spirits are still floating all over the place!
Take a deep breath and get lots of sleep... breath deep and relax... and imagine ......
and keep popping in (after you do your school work - or as a reward for an accomplishment...!)
