Head feels foggy

Has this happened to anyone else? It feels like foggy and fuzzyish kind of. Ive been on my phone all day literally because I'm off of work today and nobody was home. This hasn't happened before..

I'm going to my doctor May 2nd for a check up and I'll bring this up to him.

But my phone be why? Ugh I hate this and it makes me nervous. I have the worst anxiety over health stuff :(
