Is it so terrible to say I sleep 18 hours a day?
Oh boy! This is for real or you are jesting? It's not easy to sleep 18 hours a day. Is there a reason why you are sleeping this much?
The more I sleep the less time I have to take shit from people who don't respect me
You forgot about opportunity cost. You might have avoided shit from people but you also missed out on being able to do other things. You should live your life and stop avoiding bad things.
But people just make me cringe, it is too much for me to handle.
Sleeping so much might be the reason why they are giving you so much trouble. Try to get your body used to being awake more and doing things. That might gain you some respect back.
