<human>: Throwaway.

To begin with, I'm stuck in school pursuing a bachelor's degree in political science and global development. I'd like to start by saying that I absolutely hate my program. In fact, I hate the whole idea of a bachelor of arts degree. What's the point? It's not like you can do anything good with it. My marks certainly aren't good enough to go to law school. But...I'm done two and a half years so I figure I might as well stay in it. High school kids, unless you want to be stuck in a class full of douchebags who complain about the world and offer no solutions on how to fix it, don't take global development studies.

This brings me to my next point. I'm atrociously single. In high school, I had three or four relationships. One of them was serious and lasted for all of my senior year and my freshman year at college. In my sophomore year at college, I broke up with her. Ever since, I haven't been the same. I've spiraled into an overweight, weed-addicted bum who has lost all ambition. I mean seriously. I don't care enough to get in shape, to try hard in school, to pursue ANY type of romantic relationship...

(side story: I've liked this girl since the beginning of my sophomore year of university. Throughout the last year, became good friends. I got friend zoned. Totally still in love with girl. She totally has no feelings for me like that, which I know for a fact. Ugh.)

Reddit, what can I do to get motivated again? I've become so pessimistic and cynical about life and it's starting to really affect my future. I know alot of you are going to say something like "man up, you don't have real problems"" but I mean, this just happens to be my situation. Thoughts?

Can you summarize the given text in a few sentences?
<bot>: I'm 20 years old, in college, overweight, addicted to weed and single. What can I do to get motivated again?
