I only have one real friend and I’m in high school. What am I supposed to do?

I’m starting junior year in two weeks and I don’t know what to do about this. I want to make more friends, but I really tried so hard to do so last year and didn’t make a single new one. My friend is a senior and he’s gonna graduate this year, so I’ll be alone when that happens.

I feel like I’ve cemented my position in life as a background character. I’ve made strides to try and become friends with people at school, and for a lot of people they actually seem to like my company, but I never get their numbers or anything. I feel like not having instagram also makes making friends harder.

I get so lonely when my friend is busy and hanging out with other people. I have literally no one else to talk to. So for this whole summer, I’ve basically been doing absolutely nothing but sitting in my room, 24/7, just kinda waiting for the summer to be over. I mean, I don’t even know what I’m supposed to do. I don’t get invited to things (no friends), I can’t drive/go anywhere, and my parents both are working 5 days a week. And I even try to just take naps but I can’t fall asleep. I don’t have a job so I don’t have money, and I don’t even have online friends on discord or anything. Just the one real one.

I really want to actually make friends this year. I’m so fucking scared of rejection though. And everyone already has large friend groups. Why would they want to be friends with me when they already all know each other? I could probably disappear today and nobody’d notice tomorrow. I’m just on nobody’s radar.
