Feeling unwell day 2

This week I’ve been lacking sleep, I don’t know why but I kept tossing and turning thru the night and kept having weird dreams. I’m up at 6 everyday for work and usually go to sleep at 10 or later at night. During the day at work I seem to be fine except yesterday I had a pain in my side I guess cause I needed to poop which I did when I got home. But felt extremely tired the entire day. Tried to sleep lastnight but ended up being up later than usual couldn’t fall asleep. All day I was fine until I ate lunch and got really tired again. Felt very odd when I got home. Used the bathroom. Had a headache. Drank some tea. Took a 20min nap. Woke up still feeling exhausted 😔
