Welcome.
So you're problems in work are dealing with people? You'll find some resources here. It might help to take a vacation, but ultimately, if this job isn't for you, then you gotta find a way to change it. We spend a lot of our lives working, so if we hate that aspect of our lives...it's just not the way it should be.
My oldest brother's first job was harsh. It payed very well, but basically, it was a new company, and if there was a problem, he was the one called in. He'd end up working for 16 hour days sometimes. It killed him. So he kept the job until he could find a new one.
If you can solve the problems in your workplace, that may be the way to go. But ultimately, if the career isn't for you... it isn't. It may be somewhat established, but better you leave after 4 years then 10.
Good luck
