I feel like I'm losing my personality

Ive been in an idle state for a few months now, and I feel like I'm losing my personality. I don't really feel depressed, I don't really think about much at all. My parents want me to go to college but I just keep putting it off. I would be a senior in high school right now but I got my GED. I haven't hung out with my high school friends in months, I just have no desire to hang out with them. When I think about going to hang out with them it feels like a chore. And I'm lazy. I've just spent my days napping and playing Cod WW2 or watching The Office or parks and rec. I work every few days. It's a retail job. Ive been smoking weed more often. Honestly I dont feel anything at all right now. I think I'm an asshole to people but I don't even care, I've just accepted that I can be a bitch. Days melt together. I just can't gather any motivation to go and take placement tests for college. I don't feel like doing anything.
