Stubbornness and Skipping Meals

I totally get what you're feeling. Sometimes people feel like I'm on a OMAD diet but really I'm just not motivated enough to do all the tasks required before and after to make food (or any other healthy task for that matter). I have ADHD as well as autism and lists really do help me a lot. The best tool in my arsenal is to make a list of every single thing I have to accomplish to do this task no matter how tedious. They start to look like smaller tasks, somehow less intimidating and you feel accomplished every time you make some progress. That and maybe looking into medication might help. If it's really that bad to where you put your health at a serious risk, you may need to talk to a health professional.
