I feel I can relate to what you mean, about getting there and the anxiety about the workplace.

Friday, I had a managers meeting and needed to go back to my former location for it. I had a sinking feeling, was anxious and kept saying to myself, I hope I am not late, etc. And I realized, since I've been at my new location, I don't carry that same stress. I am actually earlier than on time at my new location, and if I am running a couple minutes behind, rare, I don't have that sinking dread feeling in the bottom of my stomach.

It's nice to not dread going to work.

Is there a person there, that stresses you? Is it the work, itself?

Not showing up, can become troubling, as far as maintaining the job. I hope you are able to work through it.
