Lonely

How do I make friends... Idk why but I seem to have not been able to make one good friend. Im going to be a senior at a new school and I’m feeling kind of nervous. Idk where I’ll sit at lunch or anything. And usually idgaf about being alone but this summer it really dawned at me that I have no friends. I’m not a meanie, or clingy, or anything. I try to be myself but for someone reason no one wants to hang out. Idk if it’s because I look ugly or something but that wouldn’t make any sense. Ugh I just need tips on how to be likable which is really sad
