I want to leave absolutely everyone behind and start over alone in a new town.
Why would you want to be alone and leave everyone behind?
I no longer want to spend time with any of them.
It is understandable to want time for yourself and start anew. But you should never not want to be around other people especially family and friends. It is bad to neglect them.
My family isn't that important and friends can be replaced with money. It's just a waste of time to spend time with them.
If you were to leave your friends and family behind, I think you'd miss them after a little while. It's rude to leave them behind anyway. Take some time to yourself and see if you are less annoyed by them.
