Girlfriend

Ok there are not many times I am looking for advice, Im more of a person who gives advice rather than takes it. However, right now I really do need some advice on what I should do. To try to keep this short, I dont really go out, I enjoy movies, shows, video games, even the occasional book, but I dont really do any of these things with anyone other than online. I work about 15 hours a week at a small business to make just enough to entertain myself and get through college (I go for psychology) but I have made no friends at this place. I hardly know anyones name! Anyway, there are several girls I would like to know better, each one being in a different class, and one being at my work. Now I have very low self esteem and do not find myself very attractive (despite what others tell me) and I gathered just enough courage to actually ask the girl from work out on a date. Of course she already has a person of interest (its apparently nothing to personal atm) but its enough to take going out on a date out of the picture. I have a feeling Ill get shot down by the other girls too, so I probably wont even bother. Im just desperate to get out and about, do something other than work and school, but there really is nothing to do. All I look forward to at other times is just making time go by as quickly as possible… Im not really outgoing, so I am not really sure what to do next… Any advice would be nice.
And just so you know, an answer of just simply getting a girlfriend is not so simple. All of the good ones are taken you know, and I can only get shot down SO many times… I plan on finishing school with average grades, getting a decent job, maybe a psychiatrist.
It seems like I just keep stretching out when I get a girlfriend, because I just can never get one. I have had a couple in the past but they were nothing serious, nothing beyond physical contact. I am just so bored all of the time… I have nowhere to go, but I am never really asked, nor do I ever ask anyone. I dont even know what the hell people like to do nowadays besides drink and I am a year and half away from being able to legally consume alcohol. Whats funny is, I was asked to a party twice, and to midnight bowling, and to the pool. I turned everyone down every time. Am I just too worried I wont fit in? Or maybe Im nervous being around people I dont know? Where do I go, what do I do, any advice would be nice!
