Nope. You just gotta do what you gotta do.
Try telling your dad you've tried to sleep earlier, and let him know it's nice to have some quiet time away from your sisters. Does he know you're on the spectrum? If he does, then let him know it may be a part of it, cause most people I've ever spoken to on the spectrum seem to be more night owls, less people and such.
