My dad is at the hospital for tests—should I stay up or go to sleep?

I do not believe he needs my help because he has money and phone service so he can call a cab if he needs to get home after his medical treatment. I usually sleep at 12-2 which is 3 hours from now and I have a busy day tomorrow so I do not want to go 24 hours without sleep tonight.
