>>1I think you should give a try, maybe you are looking it wrong. You feel uneasy, that´s normal, you don´t know your surroundings. You don´t suffer bulling, do you? I did, and I can guarantee you that your feeling it´s distorted.
You´re trapped , not by the others but yourself. Maybe you dont have friends yet but Í´m sure (and I´m pretty introverted myself) that with a bit luck you´ll persevere.
About the other high school, don´t believe everything people say, anything has its mistakes and maybe your friend school it´s not as nice as you believe.
Sorry if you think I´m sour but I´m talking taking my experience into consideration.
I have felt on the edge sometimes before, and I´m beer in your situation quite amount of time, so please don´t take it badly.
If you ever need a friend, ask, and I´m sure your voice will reach.
