This person used the term "spoons" to mean the amount of mental or physical energy that was required to do something. Someone with a chronic illness created "Spoon Theory" when they were trying to explain to a friend what it is like to live life with a very limited amount of physical and mental energy (due to her illness Lupus). Even ordinary tasks like taking a shower can use up "a spoon" of energy -- and someone with a physical or mental illness might start the day with "only 12 spoons." This is a newer use of the word "spoon" and many native English speakers will also need an explanation about it. If you'd like to read more about it: https://happiful.com/what-is-the-spoon-theory/
