Stutterer starting a new school year with no friends

Stutterer starting a new school year with no friends - I'm 16 and the school year is about to begin. All of my friends (the very few ones I had) moved to another high school and now I'm all by myself. This means I won't have any people that will do group projects with me, no one to talk to in class and no one to be with at lunch. I'm extremely introverted and the only friends I made in my life talked to me first. I'm also a stutterer which makes things a lot worse. - I just want to know how to face this upcoming school year and how to not be afraid. What I'm afraid of is to people looking weirdly at me after not being chosen by anyone for a project or something else like games in physical education. I also won't know what to do at lunch, people will look at me as well, and I'll be the only person that will be alone. I already know I won't make any friends because there won't be new people at my high school and nobody else wants to be with someone like me. I'll appreciate any tips you give me. I need help, I feel very unwell and anxious. I also can't sleep because of this upcoming school year and I think I might've developed some kind of insomnia.
