There's this thing where I feel crap because I haven't eaten (and it's happening enough that I can recognise it), and all I need to do to feel better is to eat, but sorting food out is just too much, yeah?
I can finesse it so far off there is sufficient snack food available (up to maybe peanut/honey sandwiches, but dealing with cheese is, again, too much), but I can't will myself to cook (which would properly deal with the issue for half a day or so).
It sucks! I know what the problem is, I know how to solve it, but I just... can't. (This might be the executive disfunction that I'm hearing about)
