Can't explain it

I'm starting to feel funny. Everything's there but it doesn't make sense to me. My stomach's aching with nothingness. I had a night shift but could only sleep for 3 hours after. My head spins between worry and need to sleep, yet it's so awake. Sleeping on my ever-comfortable bed feels like sleeping on bricks. I don't feel like being in my own room now. i think im gonna be sick.
