Welcome to the Forum, it sounds as if you are having a tough time at the moment.
You mentioned you wanted a fresh start in a new school. Can I ask what it was that prompted you to do this? It's a pretty big step, were your family keen for you to move?
Changing schools s never easy, even if you leave the academic stuff to one side. No support from freinds, strangers all around, and feeling you you don't belong. This of course will ramp up your anxiety condition and possibly depression too.
People do form friendships in time at new schools, I've been to 8 and it's always the same. You start of with nobody, then if you are lucky someone invites you to something and you get to be freinds with them and their friends too.
If that's not happening my was was too seek out someone who themselves seemed a bit isolated and try to strike up a friendship there.
It helps if you have a sport or other interest, computer games is a good one.
