How do I make friends?

Hi. I'm currently being homeschooled by my mother (who I don't get along with) in a really small town. I must also add, I'm posting this here because this post got taken down almost immediately in another homeschool subreddit, so please tell me if I should post this somewhere else before just removing my post if that's possible.

There are no clubs, recreational places, or areas that people my age hang out. I have 2 friends I met online, and we call and play games a lot, but it's not really the same as being there with someone physically.
I've been unsuccessful trying to go up to people and say hi, and the last time I even interacted with someone my age face-to-face they both called their friends over to meow at me??
I've tried to talk to my online friends about it but neither of them know what to suggest either. I don't meet new people at my workplace, the only high-school in town that's only grade 7-12 has someone I'm very scared of seeing again attending it, the other schools are all 1-12 or 1-6 (and I don't want to meet children), and none of the places I do actively hang out at have people my age there (Like forest trails, and art shops.)
My homeschool board does occasionally have little group activity things, but the last time I went to them, the girls (who are the only people attending that are my age) acted very rude and snarky, and I stopped going altogether when I eventually got the chance to play the piano at the church those little get-togethers were held at and they all booed me off the stage before I even got to start my song.
I do honestly want to try going back to a public school in some desperate attempt at finding anyone to befriend me, but I feel like I'm too stunted to go back (I'm at a grade 5-6 knowledge of most things and I'm currently in grade 10.) I don't want to be held back, and I am trying to get myself up to the level I should be, but I still feel like I'm not good enough to even try.
I don't really know what to do as I feel very lonely and isolated, I really want someone I can hang out with physically, and to top it off the only person I get to see is my mother who I really don't like. All of my attempts to connect with her turn into arguments, and she makes me feel pretty unsafe.
In all honesty, this whole homeschooling stuff is ruining me mentally, as I feel trapped and secluded. I heavily dislike my mother, she teaches me literally nothing, and I get no assistance whatsoever for learning what I need to. At this point I'm completely schooling myself. But that's off topic.

Anyways, please let me know if any of you have any suggestions, or if I need to post this somewhere else. I've googled stuff like "how to make friends" endlessly and nothing works. Do I just need to pray? Is there something I have to do? Am I just not likeable? I really cannot tell. I'm open to trying anything. Thank you.
