The best advice i can give to you is: stop it. Being lazy is something that is (for the most part) mental. You can do it if you want to do it. Going to bed at 2am? What are you doing otherwise? Considering you are in your last term it just seems like you have been struck down by the drag that ever other college student goes through at the end of his school life. Find a new hobby or interest that will help aid in sparking you out of bed. You only have a few more months left in school, make sure you take the time out to enjoy it.
