I have zero friends

I would just like to know if anyone relates to me in any way. I’m a teen, about to graduate and become an adult and I have literally zero friends. I went through a rough patch and moved schools and didn’t keep in contact with any body I knew in traditional school, the type of school I go to now is not one for socializing (go in, do work, leave). I don’t hang out with, talk, or even text with anyone. I’ve now been friendless for a couple years now, I thought maybe I’d be able to make at least one friend by the time I graduate but that doesn’t sound plausible anymore since I’m gonna stop going to school in a couple of weeks (grad in a month). I feel like I’ve missed out on the typical teen experience, yknow like sleepovers, relationships, learning how to socialize,etc. I have a sister and a mom readily available, so it’s not like I don’t do anything at all, but sometimes you want a connection w/ someone that doesn’t feel like it’s out of obligation. Can anyone relate? Thank you for reading :)
