Today hasn't been a good day

So today hasn't been a great day for me, and I want to know what you might call whatever this is that I'm feeling.

So I know what executive function/dysfunction is - Finding it hard to get your self to do particular things in a day whatever they may be. (In a nut shell)

However today I haven't been able to focus an anything, I'm distracted by literally everything my anxiety has been up and down for no particular reason I can put my finger on, my mind is RACING with random things that I can't even remember once the thought has left my mind and it's just making me feel burnt out and frustrated. I've dealt with this for my whole life but only being recently diagnosed with ASD and learning about the terminology and meanings behind things like exec functioning that I didn't even had a name but still experienced there's still a lot that I don't know that I want to learn about.

So as above my question is what do you call a day like I'm having today or would you just call it a bad executive function day like in my earlier post.
