I have a question for you
How much do you listen to your hunger/fullness cues?
I don't know your relationship with food but in the past I always had a good amount of rules that should determine what, when and how much I should eat. I got so out of touch with my body because intellectually I knew all the answers. Then I read the book 'intuitive eating' and it was one of those moment where your whole paradigm shifts! I realized that body and mind had to work together, not just the mind controlling the body. Also: in order to achieve optimal result s regarding health, perfection is not needed when it comes to food. Using 100% commitment (just an example) works for things like meditation, that can be easily controlled but when you are trying to control your eating with that, things can get pretty neurotic.
But again I am just assuming that making your hunger/fullness cues the priority is helpful. But I definitely recommend that book!
And good luck with the Abi!
I've already done chem and math, but still three other exams to gooo
