I agree that maybe you should talk to your grandparents about how they worked out you need to pay $400 Rent, while your Aunt only pays $200...
I wouldn't exactly blame your aunt for paying your cousins rent (while she lives with her), but if there are that many more people on your Aunts side (B/F, Daughter, Baby one the way), and only one of you, then the rent situation seems to be one of the main things that needs to be sorted out so that YOU can start saving money for YOUR future...
Just be respectful about it though, and listen to their reasoning... you may find out its coz of some of the most trivial things such as your Aunt does all the cooking, cleaning, taking care of your grandparents etc... while you might just hang out all day doing what you want (just saying, since i honestly don't know your schedule)...
So just take it one step at a time and try and improve on your current situation, then start working towards a brighter and better future... no point trying to rush from A - Z in 3 steps coz you'll miss out on all the other important steps in between...
