Becoming a boss can be one of the most challenging things, and for some it's rewarding. One of the toughest things, I've found about being boss, is dealing with all the nuances on the interpersonal side of things.

Another thing, is going from being a coworker, to elevated, and there is, and always will be those that resent those in positions of power and authority. It can also be troublesome, to change organizational levels, because suddenly those you were once friendly with, are your subordinates. And going from that lateral relationship, to one where you need to many times, make demands on them, can be difficult.

And if you are a people pleaser, like I am, drawing the line in the sand, takes courage, and guts and a ton of grit!

Did your employer give you a 'probationary' period? One where you could have stepped down, without repercussion, at any moment that you felt this wouldn't be a good fit?

To step back, with another employer, could work. When applying and interviewing, simply state that you worked your way up, and would like a job where you could start below management level, to get a feel for the culture and management consideration could be possible, over time. Or, if looking in a separate field, altogether, it actually would make more logical sense to work from the bottom up, so explaining not desire management in another field, could be a moot point.

Is the work you bringing home, more paperwork orientated, or did you mean, you are bringing the stresses of the new role home and the stress is creating a strain on relationships?
