Maybe a one-way trip to Mars could be the way to start a new life if your current situation sucks?
I'm not sure about this.
The problems are with your own state of mind. They are issues you haven't adequately addressed. And no amount of running will get them to 'go away'.
I know, cause I had similar, and had to confront them head on. And, I was successful.
Sure, return once you've got a new habit/routine in place and can confidently confront the old.
