Out of balance

I've felt really weird today. Kind of spaced out.
Time has gone by sssssoooooooo slowly. It's almost impossible to believe. It feels like it should be later, night time.
I only just went out to get some air, 4pm.

I've had a headache, and my stomach has been seriously sore. Hard to eat everything.
I feel all dizzy and kind of out of it. Like I'm not here. I keep forgetting things. And I'm constantly drinking water, feeling hydrated which means I need the bathroom more. Like every half hour.

I don't know wgat it is today.
Also for my 3 snack. I took muesli instead of cereal. I don't know why. While I was day patient, I was more keen on musli, but when I got admitted again I started to realize that muesli has more calories so I stopped taking it.
I don't know why I took it. But then as I was kind of out of it, I put the yoghurt in the plate, then the cut up pear and the muesli on top. But I don't like it that way. I like the musli on the bottom, the yoghurt and then the fruit. So I got all panicked about it. Not wanting to eat the food. There was actually tears in my eyes. But I just got on with it, tried to pull myself together.

I feel so weird today. Like I'm crying for no readon and small things are getting on my nerves and annoying me.

Maybe I'm coming down with a cold? But I don't think so.

I don't know why my body, or why I'm acting like this?

I just want to come home. I've had enough of this.

Surely I can sign myself out? Just leave this place? I'm tired of it.
