Input: Okay, I really am going to regret this later. 

Let me set the stage. I am 17 years old and I have divorced parents. I go one week with mom, one week with dad. I absolutely love my mom. We've had our rough patches, but we're close through and through.

My dad is okay. He cheated on my mom, causing the divorce. He married his paramour, then they broke up. Things were decent when my dad was single. It was just me, my dog, and my sister.

Then dad got with someone else. Immediately red flags go up. This woman is around 10 years younger, yet she looks older. Let's call her Brittany. Her and her daughter move in a week after I found out my dad was seeing someone else and I find out they got engaged a week later.

Brittany drinks a lot of box wine, leaves her things everywhere, and never cleans. She makes weird ass meals every day that rots in the fridge. She didn't have a job when she moved in, brought in student loans, and vapes with an old, disgusting juul.

She has strong views on feminism, but on a "men are pigs and woman rock!" side. My dad is a POC and she constantly brags to her friends about how she's a white woman who dates outside of her race. She always wears flip-flops and cheap, dirty pajamas and thinks it's quirky.

Brittany has a daughter I will call Kara. Kara is a clumsy 11 year old obsessed with looking older. She steals me and my sister's things so much, my sister (18) stayed with my mom full time shortly after that. Kara gets into my makeup and fucks it all up, steals my clothes and copic markers, and never cleans. 

Kara is irresponsible and told my dad about how she steals, but he did nothing. She thinks it's okay now. I have anxiety, and the way she stomps everywhere makes me panic. I told her politely to stop, and then Brittany got onto me for it. My dad only pays attention to her and ignores me, so i spend time in my room all day.

Then, to make things worse, my stepfamily and dad decided to get a pitbull. He's a decent dog, but he and my old dog, a small spitz and German shepherd mix, fight constantly because they didn't introduce the dogs slowly. My dad knew fully that dogs barking triggers my anxiety, let alone fighting, but he still got the dog.

My stepfamily never takes care of it. I was the one taking the dogs out for walks and picking up poop when i was at my dad's house. If I'm not, poop piles up in the loft and the dogs become reckless and fight more without walks. It's really taking a toll on me mentally. 

I feel really bad for disliking them, especially because Kara is only 11. What's your take on this?

Tl:dr, My dad remarried and it's tearing my life apart.

hating my stepfamily, especially my 11-year-old stepsister
