my mind is tricking me

Oh my goodness! My brain is having a freak-out because of the word food. I was typing something a few minutes ago and used it a couple times and then, I don't know, it just looked wrong. And I started wondering, "Wait, is this even the right word?" And I even googled it to see if it was spelled correctly. Now I can't stop thinking about how weird the word food is. Somebody help me! Golly, I probably won't stop thinking about it for the rest of the day.
