I can definitely relate, especially to this part. My parents also keep telling me to get out of my room, get out of the house, etc. But I have no one to hang out with and nowhere to go (I also have no money to do things with). I'm currently attending college, which you would think would be a great opportunity to get a social life, but it hasn't been so far, I haven't made any friends at all. And my parents keep telling me to join a club or something, but none of them interest me. I have three brothers, but all of them are too absorbed in their own lives to care much about mine. As I become more and more isolated from everyone, it becomes harder and harder to deisolate myself. I used to go to the bookstore or the video game store just to look around by myself (again, no money), but now I'm finding that I don't want to go anywhere at all. I'm just staying home, mostly alone.

Unfortunately, I don't have any advice. If I did, I would be following it and wouldn't be feeling useless as often. I can say that you're not alone though.
