First and foremost: .

Alright, now down to business! What you are going through with moving back in with the 'ole mom would make ANYONE (depressed or not) a little upset. I can relate to the role reversal thing; my mom acts like a child if anyone else is around so she can seem 'hip' or something and I have to keep her from spending too much money or doing something dangerous when she's being overly spontaneous. It is rough, I know that.

If you're having a hard time sleeping then I recommend (if you're not already seeing a doctor) to try some OTC sleep medicine like Advil PM--it makes me fall fast asleep. As for your mom I would have a sit down with her and tell her you're under enough stress and are capable of getting your daughter up for school--she has done the mommy thing, so tell her it's your turn.
