I think picking up and moving to another state/city is a good idea, as long as its not running away from problems, because those will follow you everywhere.
You cant run away from yourself. I understand , I've been where you have been (I think I dont know you well , but I've felt the feeling of just picking up and starting over somewhere, hell i feel it still soemtimes when things are rough.)
Why do you want to just meet all new people? Are you having problems with the people in your life? Have you burned or want to burn bridges and cut off ties with everyone in your life right now?
The idea is always appealing, but then I understand that new faces will turn into the same old problems and faces a couple of years down the line.
