living with your parents...

So I now live with my dad and step mom and have been for almost two years. They took me in when me and my fiancé broke up which I am grateful for but now its just a pain to be there. Maybe I am being ungrateful but heres the situation and let me know your thoughts..any advice would be great!!

I pay 200 in rent a month ( which yes Is cheap for most people, but again I am their daughter with a son ). Even though I work a lot I don't make nearly enough to even afford a small apartment on my own. I also pay for my own phone and my own insurance as well as grocreys for me hayden and the 2-5 other people who live in that house as well. Theyre very greeding an expect me to do everything for them. I was told when I first moved in they weren't built in babysitters..which I understand and never expected them to be. But on top of working and taking care of my expected to be a built in dog sitter chicken sitter cook house cleaner etc..on top of the 250 dollar grocerys everyother week and rent. at the end of the month im lucky if I have a 100 dollars in my account. Moms if your son and or daughter were in the same boat as where they broke up with there bf/gf and had a kid and needed a place to stay..what would your agreements be with them? Do you think its reasonable what my parents are doing and im being greedy? o are my parents the greedy ones?

    When I lived with my parents as an adult I had to help with the rent, pick up groceries (or give some money if needed for mom to shop) when asked or when i wanted something that wasn't in the house. I also had to keep my space clean. I have seen my parents go in the hole because of my brother. They are probably thinking if they make it hard on you then once you get your own place again, you won't want to come back.
