How did you cope with high school?

I'm a male junior in high school. I really don't want to be around 95-99% of the people that I go to school with. I just don't UNDERSTAND them. Everybody just feels so immature. Some people just sit there meaninglessly and stare for the whole class. Some just seem to be hypocrites and gossip behind people's backs. Some would say really mean things to each other. Can we just be kind to each other and respect each other? I also see good people being friends with other toxic people. I want to talk to them and make them see that they are friends with someone toxic. But I always felt that these people would never listen to my advice because I'm not their friend. This negative energy at school just absolutely drains my energy. I do have a few good friends though. I want to just ignore other people, but I can never do that because I'm quite sensitive to the environment and I really want to help them live a better life. I don't know, maybe I'm wrong in my thinking. Am I looking down on them? I really want to help as someone supportive and with empathy but not as someone superior. How would you cope with this?

Edit, many of you suggested finding more good people or activities outside of school. Currently, I enjoy rowing outside of school with other more mature people
