Am I wrong?! Am I asking too much?!

My older sister, who is almost 40 is majorly addicted to meth. She’s lost TEN kids total to the state between her and her ex and her and her “husband” now. She’s currently living at my moms cause her husband doesn’t want to be with her and I’m living here too. When she first came to live here I was really there for her, being her support system and trying to keep her clean just doing what I could to make her feel like life can be good without that shit too. And it was going well until she disappeared for two weeks and came back HIGH as fuck. She’s done this multiple times now and I DO NOT want to have a relationship with her anymore. All she does is ask for cigarettes, money, my stuff, and rides. I’m done with her. I’ve told her to STOP talking to me, my daughter and my husband. ( we rent out a separate part of my moms home ) and she won’t fuckin stop. Every time I see her she’s asking me for smokes, or SOMETHING. Every time I’m like DO NOT TALK TO ME.

She’s still using my make up, wearing MY clothes, stealing my husbands smokes from outside. She will not stop. I do not want her in my life. The only time she even comes to my moms is to shower eat and come down from her two week binge and then leaves again I don’t want someone like this in my daughters life. But she won’t leave me alone. I’m starting to feel like I’m wrong or being a bitch. Am I?
