HELP! No interests in life and am feeling bored, depressed, and world-weary like I don't have any use for life?

I realize one thing has always kept me trucking through life which is that I've always had an obsession. Up until recently, I've had no interests. A previous interests I've had, I've grown out of or simply have no use for them anymore. Now with no interests (not in any television, video games, materialistic things, music) I'm constantly bored. I mean, I look at what the majority does for fun on a Friday night; that is, going to a bar. Well I have no interests in drinking nor smoking and have never done that and look down on that. I have no real interests in video games. I like solving problems and figuring things out I guess and I also like dancing and dressing up but yea I don't know any hobbies or interests for me. Currently, I'm a college student all of the organizations seem kind of pointless because all of the people only go here temporarily so I'd feel stupid putting on some big thing for temporary people
