sweetie here is a huge hug.....much love and huggies

Thanks to you all! I have been wanting to have a talk with my aunt but I dont have much courage to ask to talk to her because I am afraid that she will find some reason to kick me out of the house.(its not her house btw, my uncle is paying for it) And unfortunately, I don't have anywhere else to go.

Feeling trapped and like you have no options only ampliphies the stress.  Take comfort in the fact that   You know you are not doing anything wrong...and your uncle does too.  It might be a good idea to talk to your uncle first...let him know your concerned about having no where to go, but that you feel the need to talk to your Aunt about her accusations.  I think she is misplacing the anger she feels toward her own child on to you.

I have read many good suggestions here....and i know you are feeling hurt...but I think hard as it may be for you right now...just taking the time to point out one good thing your Aunt does each day and bringing her attention to it....even something small....like your hair looks nice today....or thank you for dinner.  She might just be jealous cuz you are a good person where her own child is lost and she feels like she failed as a mom....and you are, by no fault of your own, a reminder of this.

BIG HUG!

"Thank you for dinner"? she doesnt cook food for me. She has told many times that I have to buy my own food. The only reason I would eat something she has made is if my uncle were at home and they were all eating together and then he is the one asking me if i want anything.  I try to be nice and once in a while she says thank you when i tell her that she looks nice or something like that, but most of the time she says stuff like " i saw that your room was messy today, If you want to stay in my house you have to keep your room clean."
Dont get me wrong I love my aunt but its just that her attitude towards me changes from nice to mean soooo much that it kinda gives me whiplash. hopefully I will be able to pay off some debt I have soon and I will be able to get my own place and go back to school

I hope things get better for you too...I'm sorry for the both of you that she doesn't respond to kindness and love.  As for the messy room, I get frustrated sometimes when my son messes his room up...then I remember one day when I was small and my grandma gave me and my cousins left over pie dough and we were throwing it against a door in her living room to see who's would stick the longest....my mother walked in and was mortified.  She yelled at my grandmother...why would she let us make such a mess?  I remember my grandma telling her that someday we would be grown and gone and her house would stay clean...but for now she was enjoying watching us have fun.  And we are grown...but not gone....we love to visit  her still...and her house IS always clean.  It is too bad your Aunt didn't have someone to give her a loving example to live her life by.  You can remember how she makes you feel and when you have children and their room is a mess.. (and it will be)....you will gently guide them  and not make them feel unwanted or unloved.  

Another HUG!
