Hi. I may not be of much help, but here goes nothing...
First, I would suggest you find new friends and fast. I know this doesn't sound easy, but just take some time to meet someone new. If there's anyone who sits alone at lunch or something, go sit with them and talk to them. I've been there, I truly know what you're feeling. And other than that, I have a quote that may help you. It's what truly helped me and still means the world to me this day. it says:
"As you get older, you'll gain a bit more control over everything. Don't let anyone, even your parents, break you. Find good people who care about you and surround yourself with just them. If you can't find them at first, find good music and fall into it; let it hold you until they come."
I truly hope everything gets better for you
