{{Hugs}} I think you did the right thing. Your job was a major source of stress in your life, which you didn't need. You'll find a better job, I'm sure of it. I know how you feel, the times I've been ready to quit my job was because of co-workers. I was told by a manager once that I "didn't matter" because I was "just a bather" (at the time, I'm a groomer now, but every employee should matter to a manager, I had worked there for a couple of years at that point too). Good luck with finding a job at a vet!
