I think i need a change......?

I'm not even sure if this is the right category to be writing in or what. I don't really know where else to turn. I am a 21 year old female. I have, until last semester and one a few semesters previous, been enrolled in college, although no real passion or path in what to do with my life. My major was communications/broadcast journalism, but I honestly did not have a real strive for it, and was not particularly great at broadcast journalism. My grades plummeted and I eventually was forced to enroll in community college, where I didn't do too great, I was just taking basic gen-eds. I then and still have no idea and have tried to figure out with no success a path for myself, which led to extreme laziness. I've had off and on jobs (nothing career-wise). Money went to utilities, groceries, weed (which, yes, did start a little bit of the problem, but has also helped with stress and anxiety..etc). I'm now living with my two best friends. I'm a waitress at a local restaurant in my town. I'm not enrolled in school. I just work. The same days. Every week. They don't sell alcohol. I mostly wait on old people. I bet working somewhere with a bar or something would be more fun, and I would meet some cool people. My social life is not 1/10th what it used to be. I do the same thing every day. I, like, sleep late. Wake up/get ready for work if i do that morning. One morning during the week, one or two on the weekends. The rest of my shifts start at four or five. I have the same two days off in a row a week. All the servers where I work are girls. Some of them are pretty bitchy. A few of them are cool. My best friend works there. I live with her (18) and my other best friend(21). One is in school, the one that works with me is not. I have no boy in my life at all, although I wish I had. I used to be so social. I sometimes go out, and guys do talk to me. But I'm also pretty picky. I can't help it. I don't even want a BOYFRIEND, per se. But I'm in such a slump. I'm good looking, I'm not trying to bound stuck up. I think a lot of people see me as a sl*t. No further comment on that really, I don't know. I thought about going to a REALLY good cosmetology school, but I deep, deep, deep down know it is not for me. It is the feeling I have with everything career-wise. Absolutely nothing feels right and I feel like I would have known it by now.. ? Maybe I should take some career aptitude test or something? That seems so easy. My life is boring. I wish something or someone could make it interesting for me again. I feel at times it's miserable. Am I going to be staying in a shitty apartment waiting tables the same day every week alone for my entire life? My parents live four hours away from me, now. But we love each other very much. They greatly express how much they love and miss me. I don't think they know how much I love and miss them. They moved away after we moved to the town we were in and I was in school, living with two of my friends, 18, and happy. SO i stayed behind. Which was totally okay at the time. I was, and maybe still am, okay on my own. I eventually had a boyfriend who I saw as perfect. We dated for a year and a half. We were in love. He later moved to Dallas after he graduated college. I don't know what to make of that. I honestly do not know if it has anything to do with anything (I don't know what to call this at all, honestly.) If this were a year, maybe a little bit over, ago, I would have no problem opening up to a friend or something. Between those two times I smoked a LOT of pot, which maybe helped with some aspects, but I've researched that it temperaliry rewires the brain when habitually used. I know, not the smartest idea. I know. Everything else, I don't know. Do I moved home? I don't know who to talk to. I'm sorry if this is stupid. I just don't know what to do.
