I want to leave everything behind....?

Alright, this is elaborating on my previous question. I really want to move away from my town in Michigan, and move with my dad in Alaska. The reason I want to move is b/c I feel like I need to escape all of these familiar faces. I've blended too much into the background, and I want to step out. But I can't here. I think that if I go somewhere new, I will have confidence to be myself, not the quiet girl. I feel kind of depressed all the time b/c i'm not the vibrant, brave person I want to be. Do you think I can become the "new me" in Alaska? Also, moving would mean leaving my mom all alone, do you think she could cope?
