Has anyone here felt this way before?

Hi, I'm a 17 year old gay male. I go to a catholic high school, and I have not come out to anyone, even though i know some of my friends would be accepting. Anyway, I just feel very frustrated sometimes, because I feel like I'm missing out. I accept myself, and I'm excited to be more of myself in college, but I'm just frustrated right now. I have no gay friends, no one I can really relate to, and no way to make any gay friends since I don't feel comfortable coming out in my environment. The only person I know who may (or may not) be gay is a freshman, and it would be weird for me to try to be friends since (1) I'm two years older than him in high school and (2) he may not even be gay or have come to terms with it yet if he is. I'm not really asking for advice, since I know there's nothing I can do except wait for college, so I guess I just wanted to let my feelings out and see if anyone is or was in a similar situation.
