Hi girlplayer34,
It can certainly be frustrating to feel like you're the only person who hasn't yet found a partner, or like the people who are telling you to be patient how urgent it feels. The tricky thing is that, while you can certainly do things to be an active participant in finding a partner, at a certain point being patient is just part of the deal.
I wonder if re-framing this situation and changing what you tell yourself about it would be helpful. For instance, framing being single as a disease is going to hurt you in the long run, even if it feels emotionally true right now. After all, it isn't contagious. Too, being single offers a lot of opportunities for positive things to flourish and for you to really enrich your relationship with yourself. You can read all about how to do that here:

I do want to add that, in addition to it not being that unusual for someone to get to 22 without dating, it's a pretty common experience for queer folks to find dating in high school or college to be a bit trickier than it is for their straight peers. Other people being out, their own ability to be out, and the size of the queer dating pool in smaller schools can make all of that trickier. In fact, we have a whole advice column about being a single lesbian wishing for a relationship:
