Remaining a virgin until marriage and dealing with loneliness?

I’m 19 years old and I’ve decided to remain a virgin until I’m married. I’ve had no success at getting a girlfriend in my entire life. My only two social outlets are college and work. At work, all the girls either have boyfriends or they constantly talk about (as in not-exclusive and very promiscuous). At college, I’m practically invisible and most of the girls are either married or in a serious relationship. I wonder if there is anything I can do about it or how I can deal with being alone for the rest of my life.
