How to deal with my overbearing cousin?

I just wrote the whole thing. And it didn't post. Ughh.
I guess I'll shorten it.
My girl czn has been sleeping on the floor. Today she pushed all my stuff over and like put her stuff on my bed. I suppose she'll be sleeping on the bed tonight.
For the...

last 2-3 weeks, she's been pushing all my stuff over. I wake up and all my stuff it pushed over. I don't say anything to her. I just pick it up. But she's gone over the edge.
Although, I'm not going to go to my mom and tattletale on her. That's what she does. She cried to HER mom and her mom comes to me telling me to do sh*t. She talks sh*t about me.
I'm not sure what to do. I dont want to sleep with her. I want to go downstairs and sleep but that's like showing her that she can get the whole room. NOO. She can't.
After all it's still MY room. MY house. Even though her family is living with us right?
As I'm writing this, she's pushing my covers over so she gets more room on the bed.
I'm not sure what to do?
What would you guys do?
She doesn't speak English, so I have to talk to her in Chinese which is harder.
I can't stand her anymore, she's gone over the edge. I feel like I'm going to kill her.

I think if you really want the problem to stop...then you need to go to your mom and tell her. You can't solve the problem yourself espically if you don't say anything.
And please for the love of god...don't kill her cause you think you don't have any space now think of what it would be like in prison. (not saying you would)
Good luck

Talk to your mom, but tell her not to make it obvious that you told her, you're right it's YOUR room, YOUR house (well, actually it's your parents house, but you get my point) stand up for yourself, if you really want to stop it for good, tell your mom, when she's pushing stuff off your bed while it's happening, the your mom can wa;lk in and it's totally not obvious (just make sure you don't walk in the same time, right before, or right after your mom talks to her)

I dont think my mom wants to confront her.
She'll probably throw a fit and cry.
*sigh*
My mom already knows I don't like her though.. more like hate.
We can't really do anything about it.. I mean after all she's still my cousin and my uncle is still my mom's brother.

Oh, it doesn't seem that bad to me. Sounds like she has bad bed manners, but what else? Could there be another reason that you don't like her?
Do you feel threatened by her?
Just let her know, in Chinese, that it's your room and that you don't mind her sleeping with you, but she's going to have to sfay on her side or she's going to sleep on a pallet on the floor.I grew up with 3 brothers and no sisters. I wished I had a sister to talk to. Isit hard to talk to her because of the language. I bet it is hard to learn Chinese.
I wish you luck with this but, really, it just doesn't seem that bad.

Tell her that is you f*cking room and you decide what happen in Your room in chinese, he,he. Ok if she still doing the same just slap her in the face so she can understand you!!!
