Movjng hometown?

How would you move out of your hometown? I’ve been here for a while, sick of family and would rather just move away with my son and obviously visit whenever I’m up to it (because they wouldn’t come to visit me as I already know this😴)

I’ve been wanting to move to a different city for a while but I have no idea on where to start, what to do etc?

Can anyone help?
