Here is the thing
There is no such thing as starting over.
You can move somewhere else, that's a thing
You can make new friends, you can drop old friends, leave your job and/or get a new job.
There are lots of things you can do to give what may seem like a fresh start. None of those things actually are a fresh start though.
They are just new scenes in a series you have already lived.
Don't get me wrong any of the above things can be helpful if they work for you. Still, that's not starting over it's moving forward. Also good but not the same thing
