Am I The Only One?

I had to take a vacation from work. Life on the ambulance was overtaking every other aspect of my life. I was thinking about work constantly. Being woken up in the middle of the night, heart racing, sweating, because I was dreaming about work. It's my full-time job that does it to me, though. I only have nightmares about that place. I only act like a raging lunatic when I'm at that place. I'm calm, collected, and almost zen-like at my part time job. Am I crazy, or is the environment where I work that toxic?
