I would like to say I totally feel for you... BUT I don't. Heres is why... When you move out, are on your own, you will be really well prepared to be self reliant and self sufficient... That being said, try this...
My mom lives with me too...
I do all the following...
All cooking
All cleaning
All yard work
All laundry
All shoveliing
All driving
Only person to work in the house
All animal care
All shopping
All garbage take out
AND I have 2 little boys. It sucks some days yes, but, life is what you make it. So, don't complain to much. It could get a lot worse. You could have to walk home instead of getting picked up.
On the days you volunteer, which is totally awesome of you btw, be prepared to open a can of soup and grill a cheese sandwiche. Easiest meal ever and usually everyone is still happy.
ETA: I just saw the posting that were made before I finished submitting my post... If 8-10 people is the case... WOW. That is a load of crap, and maybe you need be really tired when you get home and make a sandwich and go and hide! I have only to cook for 5.
