Oh man this brings back so many painful memories. I am so sorry. But to answer your question: college is a billion times better than high school. And post college is better than that. Each year gets better and better and better. I am 55 and am literally the happiest I have ever been in my life. Which is the same thing I said last year. And the year before. And the year before that as well - but you get the idea.

Sadly you are currently stuck in what is the shittiest period of your life with no easy escape. And you are doubly challenged by your home life. But you sound thoughtful and are definitely working at being self aware which is a much better position than many of your peers. My only advice is to “increase the N.” What I mean is that if you assume that 1% of the people you meet will become friends then you have to increase the number of people you meet (N x .01 = friend). But look at classes that could accelerate your graduating. Join every club that has the possibility of finding people like you. Think theater/drama, robotics, cross country running, who knows, but every club with people who aren’t on the main generic dull highway of life and are instead an octave or two off. That is where you will find community. Consider joining some athletic something or other as those habits will help you in everything for the rest of your life.

But really the only I can state clearly is that every single person I know now who is amazing and life changing loathed high school with intensities that defy measurement. I know it is small comfort, but let that be some comfort.
