Thank you all!!!!! I told my boss. She handled it WAY differently than I imagined she would (considering earlier that morning she flipped out at me over something another co-worker did that I had no part of... and again over something else unrelated to me... and by freaking out I mean pulling at her hair shouting at me behind closed doors mad). She made it very clear that I am welcome back at any time if this doesn't work out. She announced it to the staff Friday (it was my day off) and everyone was pretty bummed to hear about it, but everyone is very happy for me.

I start January 2 at the new job
