Always surprises me how people think leaving will help them, You don't have a win/loss ratio here to upkeep so you can be away 11 months & it'll be much the same. Don't sweat it.
But if you want something to change, i found, sometimes you have to be the change. Instead of doing what some people think is the cool thing to do & ditching everything/one, sometimes you just gotta do what i do. Figure out what you can fix, or prepare for, and don't sweat what you can't change. Just one bit at a time, & one day, even if nothing worked out the way anyone hoped, it'll have worked out. Maybe not a way you'd like, but an eventuality.
