Long post but please read. I can’t handle fights like this anymore. Idk what to do 😕

My sister brought her dog over and she knew I was mad. A little background her dogs a grate Dane mixed with a lab so is huge and hyper. She has broken many of my things and is supper crazy and knocks everything over and my cat is terrified of her so it makes her hide for the rest of the day even after she leaves.

I told her that having the dog there makes me mad, stresses me out and gives me anxiety. She then told me that those are not reasons to not want her there. She kept saying I am Not at all affected by her being there. Yet those are my feelings and she is completely brushing them aside. She went in the basement with Her 4 year old daughter and kept yelling at the dog to stop and let go of something. When I went down there to switch my laundry she was using my blanket. So I took it and said that I don’t want her chewing on my blanket and putting a hole in it like she does with every other blanket. Not to mention when I took my blanket it was wet with slobber obviously chewed on 😑 She called me a bitch and a cunt ect. I was on my way to bringing her a new blanket when I said she had to move the car to let me out of the driveway bc I had to leave. She said she’s not letting me out bc I’m being a cunt. I said I was going to put The dog outside until she moves the car. She still wouldn’t move it. So I said I would throw her stuff around the room. Yes I know that was very wrong. And I apologized for both of those statements but I didn’t know how else to get her to let me out of my driveway. I told her she can’t just come over here and block me in and refuse to move the car. I said I was going to Call the police and she said she was going to call the police and have me committed to a hospital against my will. I said for what?! She said delusions that she is trapping me in my house. Confused bc that’s what happened!! She came over and blocked me in and then refused to move so I could go to school! lol she then continued to call me crazy and names. She then called my dad and told him that I’m freaking out and scaring Her daughter (my niece) saying I was going to call the police. When she’s the one who said she was gonna call too. She said I scared Her and she doesn’t want her around someone unsafe. HOW AM I UNSAFE FOR YELLING AT HER TO MOVE HER CAR?! Her daughter is hearing all of this and becoming more afraid of me. My sister doesn’t admit that she does anything wrong and continues to tell ME how unacceptable today was. And of course my dad believes every word and thinks I’m this big mean person. I tried to tell him my side and he just argued with me every step of the way and argued everything I said away. They both think im crazy and wrong and a shitty person. And I know someone is going to ask so I am gonna say Iv told her not to bring the dog there but it’s my dads house so she is welcome and so is the dog (my dads words) Not the problem but she said i was a cunt for taking her blanket away and being mad about the dog chewing on MY blanket. I’m just really upset and stressed that fights always happen where I’m this big bad person when I think I have reasonable reasons for the things she gets mad about. I’m just so defeated and hurt that this is my only family alive and this is how they treat me.
