As Buckaroo Bonsai said "No matter where you go, there you are."
You can disconnect and cut yourself off from all the people and places of your past except for one person. Yourself.
You will still be the same person and all the mistakes you made in the town you grew up in will will be the same sort of mistakes you will make in some new place. But facing those mistakes, you stand a chance of working through them and growing into a more effective person. Disconnecting from the people you know now will not change how you deal with people. It will only change the names of the people you deal with, but you will still deal with them in the same way unless you change the under lying problem of how you deal with people. And if you can do that, there is really no need to disconnect.
