Q: Mouse not working

My MacBook pro is going crazy. The mouse is moving sporadically all by itself and clicking random things. Anytime I try to use my trackpad, it just makes the problem worse, making my computer worthless. Tried disk utility to repair, but by the time it was almost done repairing, the mouse went crazy again, so I have no idea what to fix. I've also restarted my computer and it didn't fix the problem. Any suggestions on what to do? I don't have an apple store near me.
