It’s great that you share both the excitement and the anxious thoughts on your journal! 
Just based on the small amount of psychology I’ve read in the past (I’m not a psychologist) and my own experiences, I feel like the most important part for you would be to plan your refeed carefully so you’ll know that you get an adequate amount of food to give you enough fuel, so you can minimise the risk of it turning into a binge.
I don’t recommend counting calories long term, but I can be a good tool for just a few days to get a grip on the amounts of foods you need!
The constant evaluation and thinking about restriction or worrying about under eating/ compensation can be very triggering, and it can be a relief to just know that you’re having enough.
And try to keep relatively busy while refeeding too, so you won’t be consumed by thoughts on food, whether they’re restricted or binge triggering! Food is fuel, and it can be very enjoyable and anxious-free once we manage to build a healthier relationship to it!
Wish you all the best!
