I was tired but got woken up…

I fell asleep quite quickly but ended up getting woken up by my cat wanting to come in the window. I also keep having to pee again. That is getting really annoying because it disturbs me every night. I have a headache coming on and just feel really off tonight. I only had 700 ish calories yesterday which is probably no where near enough. I ate a proper meal so that was something. I can hear a loud whistling in my ears which is so intense.
