Yeah, I can sometimes become nocturnal. I sleep much better when I am not under tons of stress/living in fear but in the current state I'm in, I'll be up until 4-5am and then sleep until 10-1pm. I think I do that partially to avoid my parents and because the house is only peaceful when everyone is asleep. But it's terrible when I have to do something on normal human schedule. My mom scheduled me to do something at 9am on Monday and I don't know how I'll make that happen.
