A few years ago i had trust issues too, i couldn’t trust anyone.
I think if you start to have more confidence in you , you will trust more easily in people, at least that happened to me.
And yeah some people are just looking for a good story to hear but i’m sure your good friends aren’t, they are here to help you.
About the new school: try to be funny, nice and don’t pretend to be someone you are’nt, just be your beautiful self and eventually you will have some good friends that you can talk to without being afraid of teeling your secrets
Hope I helped beautiful!
