I go to a small private high school and I’m not attracted to any girls there. None of them even share my interests or anything (I like to read fantasy novels and listen to classical music). I’ve never had a girlfriend or kiss because of it and I’m already super depressed about it. Will it be easy to find a girl I can identify with in college? I’m freaking tired of being single.
Finding a girlfriend isn’t like finding a phone you like. It’s as much about being the right person as finding the right person.
The first thing you need to do is get over being “super depressed about it.” You’re right in there with a good percentage of the kids in your graduating class, regardless of what they lead you to believe.
As to finding a girlfriend-- and a group of friends in general-- in college: you’ve got to put yourself into places where that girl and those friends are likely to be. So cultivate that love of classical music-- find a group of other enthusiasts. The fantasy novel thing may be a little trickier, or it may just be that it’s so far from my taste that nothing occurs to me.
But you need to be yourself, but your best self. That girl isn’t going to hunt you down. So you’ve got to break out of your shell and let her find all those things that your mom and your best friend and your grandmother love about you. You’ve got to put yourself out there.
Book Club? (But don’t be like the guy at my involvement fair who said our selections looked uninteresting because he normally read epic fantasy novels consisting of over a thousand pages each…dramatic pause…in JUST DAYS. That condescending attitude won him no friends at our table.)
Dungeons and Dragons league? Ren fair? LARPing? Take a class on fantasy literature or films?
Your priority is supposed to be your education. Go to college to further your ambitions. Your girlfriends and life partner will be there. The girlfriends will materialize as you get to know people in your dorm, your cafeteria and your classes.
Don’t be in a rush for a girlfriend. She and many are out there for you.
If you try to artificially make a relationship happen, it won’t work in the long run. As you delve deeper into your major in college (do you know what you want to major in yet??) you will find people who share interests and you will be naturally attracted, which is what you want.
I have a HS daughter who is a junior, prefers classical music, and is an avid reader. She has yet to date, partly due to a limited pool in her small HS and partly due to lack of time. She is an attractive girl. I am confident that she will find kindred spirits in college and you will too.
No, I’m not trying to set you up! 
You might want to seek a college or university that also has a strong music program or conservatory to increase your chances of meeting classical music lovers, for friendship or more than that. Or check to see if there is a fantasy/sci fi student organization on campus. If not, you could probably create one yourself.
You could always go the inflatable route.
There’s usually at least a few women who you’ll meet in college who will be suitable for you or share your interests. Once you start taking classes, make a point to sit next to women that you find attractive. It’s likely, especially in college, that you’ll be paired with her for a class assignment that involves teamwork. This is very common, and it’s a good opportunity to meet women. I’ve done this many times and met some fantastic women.
Aside from what I mentioned, like others have said, join some clubs that cater toward your interests. But if clubs aren’t for you, there’s plenty of other places: Library, dorm room hall, cafeteria, local bars/clubs and etc.
I personally say never look for a girlfriend. Live your life do the things you enjoy be happy with yourself and fully accept who you are. Once you do this people will come, women will come. Pursue your own personal happiness and people will gravitate towards you. I say this because relationships can be messy so you have to have a personal foundation. The last thing you need in college is to be stress, upset, or sad especially in regards to a female, its a waste of time.
