try Jolt's suggestion and join a team. even the chess team, if you have one. go out for a run. make it habitual. work out, excercise, read books.
dont concentrate on what you dont have. concentrate on what you HAVE.

i take school online, and i do baseball. its boring and no one on the team likes me either.

Kid, you don't need your computer nor your XBox. You don't see everyone in Africa depressed because they don't have XBox, do you? As I said, do your best to focus on school and GET yourself into a collective sports. These two things together give you much to handle.

yah and people in africa have never brought thier 8th grade science grade from a 21 up to a 91 in 3 weeks to earn a xbox or computer.
