Hi TJ, sounds like good advise from your T. Everything in place including routines with some flexibility, for one day at a time. And try not to worry about work right now as well , "early days"!!.
And TJ, when you're writing in your journal don't forget to write the positive things down as well!!
I know that worries, concerns, uncertainties the "less positive things" can stand out so much more sometimes. And they are important to record/address, but the positive things really matter too. And I also know, you can really "undersell" yourself sometimes too!!
