I’ve literally only been awake 4 hours today

I’ve literally only been awake 4 hours today, I had to force myself to eat, all I managed was a donut, some popcorn, then after sleeping for another few hours I managed to force myself to eat a few ravioli and a small mozzarella stick. Now I’m going back to bed. I can barely walk, I have to use things to hold onto. I’m dizzy and my head hurts. Yeah. Idk what’s going on, this feels like something more than regular fatigue.
