I can understand. Maybe try some sleeping pills?
I never tried any; my sleeping schedule was absolutely destroyed during the worst period of my life, and now I have panic attacks if I don't sleep long enough, lol.
But, really, good sleep and rewarding yourself even for smallest achievments are crucial and can be the difference between normal and terrible existense.
As people mentioned here, you will indeed be treated better. It also means that if someone would end up bothering you (unlikely), you will be able to regulate this issue, because your voice and opinion will matter much more. Good point to start treating yourself better too.
But I think you know all of that already. I just can't pass up the opportunity to chat a little, I guess.
