I'm such a depressed high school senior.?

I have two more months of high school left and I'm not sure if I can handle this anymore. The school I go to is half across town because the neighborhood I live in has become run down. The public school across the street has become dangerous, so my mom drives me across town to a much safer district. During my 8th grade and freshman year, I went to the private school across the street, but since I had little to no social skills, everyone there was either indifferent toward me or just plain thought I was stupid. I made no close friends as a result. Afterward, I attended the public school I mentioned before. I've grown tremendously as a person and many people now recognize me as an artist who draws people. I want to become an animator and work for a Studio Art BFA degree in college. But people don't realize that I'm depressed, lonely, and sexually frustrated. I will never come off as weak when you see me. I hide all the pain that I feel because I don't want people to talk down to me or think that I'm worthless. I live too far to adequately hang out with people, I don't drive because of bad circumstances, I don't have any friends from the past because of a bad freshman year...and every relationship I've wanted with the girls that I've liked have failed due to my own emotional weakness. Almost all of them have hooked up with somebody else that I know---it it secretly makes me feel even more alone. I feel forced to put up a confidence front everyday just so nobody can think I'm weak or fragile, but I feel very depressed and angry about my high school life and just want it to end. I'm not even attending prom, because I just few it as a drunken fest that isn't even worth going to without real friends in the first place. How can I make it through the next two months? I just want to start over at college.
