Changing places doesn't "heal" you, but it does get rid of a lot of outside stresses. You still need to address certain things perhaps. But of course, that might actually be easier in a new place. Sometimes others really are the problem. Sometimes the stresses of certain people and the place where you live and really wear down on you.

It certainly wouldn't hurt a lot of people to go to places where they can actually afford medical and be able to get help with mental care...which we don't really tend to realize that everyone kinda needs to a certain degree. Maybe everyone doesn't need medication or even a psychologist, but they do need guidance. It's just that often we rely on friends and family for some of that. But sometimes they suck at it or you can't really talk to them about it.

Or sometimes people can't get a good job where they're at.

Or they live in the middle of nowhere and it's a pain to even go to the store.

There are a lot of stresses that moving can change...even if it won't deal with your personal issues. Of course, it might allow you to deal with those issues, or at least recognize that no, it's not because everyone around you is a dick, it's you.
