I am having trouble finding true friends and I start high school next year. I am an introvert but am horrified at the thought of being alone?

I am a straight A student. I am a Christian and follow good moral beliefs. Every teacher or adult I’ve encountered has always complemented me and my parents on my behavior. But throughout middle school, it has been very difficult making and keeping friends. I moved here in 2018 so I knew literally nobody and had to start on a clean slate. I was very social in sixth grade but over the span of two years I have lost my social outlook and have become an introvert. I switched schools in 2019 and I have a lot of regrets. I have found people who I can joke around with and sit with at lunch but I’m not sure if I would consider them friends. Nearly everyone in my school has moral beliefs contrary to mine and many kids flaunt about illegal and overall bad things. I feel horrible being surrounded by such negative influences on a daily basis. I start high school soon and although there are people I can joke and talk with, i don’t know if they would consider me a friend and I am horrified at the thought of being in a large high school literally all by myself. I don’t know what to do and I already have Generalized Anxiety Disorder so the stress is nearly doubled. No one likes the music I like, nor any of my interests besides my sense of humor. I constantly worry about what others think and I know I’m trailing off but I’m just scared. Please give me any advice that could help me because I’m addition to having anxiety and being anti social, I definitely do not want to be left out. Thank you
