Congrats on a week!
That anxiety the first few weeks will definitely wreak havoc on one's thinking. I was ate up with it.
I had good results by breaking down the feelings a bit, dissecting them, putting them in a box, and being OK with them. An example might go like this:
Instead of "I am resenting Tim" I would change it to
"I notice I am feeling resentful because Tim was talking crap behind my back, and that's OK."
Acknowledge it, give it boundaries, accept it.
If you want to go the extra mile, add some gratitude to the end,
"I am grateful that Tim was thinking about me. It shows he cares, even if he didn't express it very well."
Best of Luck on Your Journey!
