I'm In Love With My High School Crush, What Should I Do?

Last year, I was a senior in high school and this was my most memorable year of high school because growing up I was a shy kid and in high school I started to break out of this shy kid bubble I was in. During my senior year of high school, I met this girl who was a junior in one of my classes and talked to her a few times that year. I didn’t know it then because I was busy crushing on another girl, but that girl I met was the PERFECT girl. We both share the same religion and we both liked similar things. I fell in love with her in my second semester of my senior year, but sadly did nothing about it because I was still at the time I was nervous to conversation with her. Now in college, I assumed I was gonna get over this girl and start to like another girl, but I still think about this girl a lot. No girl can compare to her in my eyes. I still live home because I go to a community college that is still close to my home and high school. I visit my high school time to time to see my old concert band perform and possibly other events. Through my high school’s social media, I discovered she got accepted into a university that is 5 hours away from here. Heartbroken by this, I still can’t seem to let her go. What should I do? I know things will be different if I see her again and I won’t have any trouble approaching her. Should I try to see if I can possibly bump into her? Should I make a Instagram account and follow her because she has over 900 followers? Should I tell my friends who might know her that are still in high school that I like her? What do I do?
