I feel like I'm becoming messed up?

That's just how people are. They don't mean to hurt you. They're also hurt by the move and the thought of losing you, but that doesn't excuse your best friends seemingly heartless. behavior. Your mom probably doesn't like the move either, but won't admit it, and the fact that you don't like it is just her way of venting her own anger. My advise, focus on your best friend. If you leave things as is you'll never get another chance to fix it, and you'll regret it untill you forget it, wich might never happen if she means something to you. Tell her how it hurts to feel like you need to be replaced. She shouldn't think you do because you should just be in her heart as a friend. You need to tell her you'll remember the good times and never forget her, but don't tell her to do the same. Just let her think about that. She'll regret ever treating you that way if she doesn't apologize before you move.
