Ooh you are desperate.
I can't imagine what it is like to be moved without wanting to.
Do get an old friend over to stay for a weekend, maybe your parents can pay their travel expense?
Then you can explore your new town togrther, maybe go riding together. Or visit some local shops together.
But also you need, for your own sanity, to let the new people in too.
Join a local club, nothing competitive just fun, that is always a good way to join. It might be the local gym/leasure centre, something run affiliated to a church or school related. Don't stay locked behind your phone, no matter how safe that feels.
What activities have you been curious to do ?
Best of luck and be brave.
