How Do I Not Let My Pathological Liar Roommate Effect My Mood And Make Things Less Awkward?

my roommate never paid me rent in september. What she then said is she would pay all the rent in october and would bring me a recipt. She brought me the receipt and everything was cool. Then in November december and january she said she paid with money orders and i was to give her my half of the rent. I did every time and she gave me receipts ever time. About two weeks ago my rental place called me and told me i had not paid rent in four months. It’s a huge complex. They said they sent me letters every single month but i never got one. I then had to go pay the rental place 3000 dollars in backed rent before i got evicted. After i cleaned my room i went back and showed them the reciepts she gave me. Thats when i found out the receipts were fake and she had been taking my money from me all these months and not paying rent with it. She was never on the lease because she was not approved to live there so i took her in at my own risk knowing that i may get in trouble for it but her and her son had no where to go.
I finally got her to confess she did it and i got something signed an notarized that said she took the money and if she did not pay in back in full by 2-27-09 i would press charges and sue her.
Now she doesn’t clean up after herself she leaves stuff all over the place and orders an insane amount of pay per view knowing she won’t live here when the bill comes
i just feel so taken advantage of i’ve covered for her again and again and helped her out when she needed it. There is nothing really more i can say about how mad i am but everytime she is here i want to rip her head off. She legally is allowed 30 days before she has to leave so i can’t even force her to go.
Also when this whole thing happened when i found out that rent wasn’t paid she called my bawling saying she just lost her job. I found out a couple days ago she never even lost her job she still works there.
She also told me she was in the hospital all these days cause she was sick…yeah never there so i know she has a serious problem with lies
and she had the nerve to ask me if i wanted to buy the washer and drying off her (which don’t work) for $500
How to i make it so i am not filled with rage every single time i am in my home with her?
