>>1 I know what you're going through only Too well...
You need to either get out, let some energy out each day before studying hardcore (like going to museums, seeing a play, hanging out at the theaters or an arcade, a walk in a botanical garden, look up your city and try out an unusual event).
ORRR... Calling up some friends for a study group, and just pray it won't wind up like the one in Community.
You don't have any friends in these classes?
