UPDATE ON THE SITUATION
My aunt (who has two boys) feels that now that there's a girl in the house she can make up for all the house work of sixteen years by transferring it to me. I go to college, I have to study, I'm trying to work, but she doesn't see it that way. She sees me as a burden to her life that had better be grateful that she isn't giving me even more work. It's got to the point that I don't eat around her anymore. I sneak food out of the kitchen when she's not around because whenever she sees me eating or drinking water, she finds something nasty to say about how I'm wasting her resources/money/food, etc.
I don't think the 'treat me as her own child' thing is gonna happen. She finally came out with it and says she doesn't want me in her house anymore, which is great news as far as I am concerned because I've already made plans not to be anywhere around her. My grandma got really upset and burst into tears though, which hurt me and infuriated me at the same time because I love my grandma to bits, and I can't see why her daughter should put her through so much drama.
I guess I'll be okay somehow. I mean, I'm eighteen, but we do have to go through these things to become better people don't we?
Still in pain from seeing my Grandma cry, but cool otherwise.
