Okay I actually cannot stand living with people!!

Five months ago my mum brought my cousin to live with us from the Philippines to AUstralia so she can study and work here. I love her and all but after five months living with her I cannot stand to even see her without throwing an axe at her. The things she does just annoy me, and what really is weird is that it's all little. I think I actually have a problem living with people, I just cannot stand it. I think it's the differnt cultures that a forced to be mixed together. I don't know but you guys tell me. 
. 
1: firstly she just barges into my room like she owns the place, and when I'm on my bed she lays on it for a long time. Usually she does this after she finishes work (She's a cleaner?) all thoes germs are onto my bed now! Also I hate when people bardge into my room, like what if I'm doing something private? (I didn't mean it like that!) but seriously would you like it if someone just came into your room without any alarm. I understand I have earphones in but don't just barge into my room without knocking unless theres a murder in the house or our house is burning down. Like she can't invade my private space, this aint your house girl! nor your room. Not only my room but the bathroom to.

2; I hate how she borrow my stuff. Okay I admit I'm a little fashionista, I work a part time job and I work hard to save up for these expensive branded clothes. Yes, I follow styles and brands it's what I do, it's my hobby. I understand my cousin doesn't have any clothes and she has to use mine, I understand and I do let her. Buttttttt! I don't like it when she keeps it in her room for ages, or just never gives it back. I hate it how once again she barges into my room sometimes when I'm not there to use my clothes and stuffs, like she use to text me and tell me she's using my things but now she goes into my room and doesn't even tell me anymore. I also don't like it how everyday she usues my things, I mean she's been working awhile now, doesn't she have enough money for clothes? Like I spend hundreds or dollars of clothes and I work hard from it, but it looks as if she's benifitting more out of it then I am. What I hate the most is that all my clothes are colour catorgizer and when I come home I find it all messy becuse she has messed it up.

3. I hate the messes she makes, so my parents think shes some angel because she washes the dishes and cleans the house in front of them, but so do I. I cannot live in an untidy house so I'm always cleaning. But my cousin always leaves hair behind, the stuff she doesn't like eating (like chicken bones, ginger) she leaves it on the side of her plate and never picks it up, I have to. 

4; Since she is going to school she has made friends and now all she does is text them or be on the phone to them. I would be telling her a story she wouldn't be listening she would be texting her friends on her phone. And sometimes when I'm watching my shows she would sit on the couch just texting then she would be on the phone to them and talk as loud as my TV show. Like seriously and she would stay there for awhile. And when I;m watching SBS Pop Asia she would come downstairs and force me to watch something else,like don't you see I'm watching TV? 

There are more other things I hate about living with her, I hate how I plan out my day and she always ruins it by spending time in the shower and I can't get to it. When I come in it's all messy like her menstral pads are on the sink and . I kinda admit I have OCD and when things and time don't go right I go crazy. I admit I actualy have problems, and living with my cousin is no the first time I occur with these problems. Like when I went to Italy with the school, I hated staying in a hotel with people. Or when I was young we had students living in our house that would give us money. I hated them living in our house! I would always sabbotarge them into wanting to leave. 

I know I am a but I just can't live with another person who posses more germs then what is needed in the house. I know you can hate me but I honestly cannot stand living with someone in the house.
