It's funny I'm almost in the same situation as you I live in the UK im 19 all the friends I had been with in the past I could honestly never trust completely personaly tho I think that with a lot of people that clame that they have good friendships are bluffing why is it you see with some people that they laugh extra hard at each other's jokes or make a big deal out of trying to make somone feel good in order to not damage there feelings there intended not because there simply being honest but rather to sustain that relationship you should ultimately trust in a true friend as if you trust youreself.
You say you live in the UK im from Somerset near tounton if you want me to reach out to you give me a shout my facebooks harrison west I'm on this self actualized journey with you.
