Advice: 22 years old never been in relationship.?

I have been pretty shy throughout my life which attributes to my being single my entire life but lately as i have been working really hard at breaking it and do really love myself and think i am a very beautiful and intellegent girl can't seem to find someone that would even consider being in a relationship. i am an extremly caring person and will be the first to admit that i tend to take care of my friends before i take care of myself. I have always been struggling in this region i care way to much what people think. The thing is i really do like one of my friends but he recently moved about 2 hours away and straight up told me before that he doesn't do long distance relationships when i was talking to him about one of my brothers friends who i was "talking" to but he turned out to be a complete jerk when i told him i needed to focus on school for a while which sounded reasonable to me becuase he had gone a couple of months without talking to me but yet when i said i couldn't talk he said i needed to reevaluate my priorities. thing is i am in my last year of college and it was last round of midterms and finals month so i was super stressed to do well on those exams. everyone else understood but him. i guess what i am trying to ask is will i always be this lonely a lot of my friends are in long term relationships and don't understand what i am going through and when they try to make it better end up making it worse. any advice what to do?
