<human>: Can you succinctly summarize the text in 1-3 sentences?

Okay I got to get this off my chest. I'm 21 F and I have one older brother who is married and lives on the other side of the world. I love him so much - we are really close so he's practically my best friend. I have an older sister who is 30 F and I am just so pissed off but we don't get along with each other at all. Fuck this makes me so angry to even type this out. 

I go to a university that's about five minutes away from me so I live with my parents obviously to save money. But my sister is still living in the house for some reasons that I do not fucking care. She always COMPLAINS and talks too much but what I baoslutely hate about her is that she's EXTREMELY negative. Always points out the littlest things. For instance, if I forgot to clean the counter, she would tell my mother who will tell me to clean it. DOES THAT FUCKING MATTER?????? Not a problem, I deal with this every. single. day. 

She has a job so she contributes to the rent bills or whatever but please don't say, "well she should move out." That's not within her possibilities but what's pissing me off is the way she is. She's so negative and talks too much.

I'm extremely jealous that my mother and my sister are so close to each other. That's what fucking bothers me the most. I want to be close to my mother but my sister has to get invovled. What the fuck. Even when I talk to my mother, my sister always fucking interrupts the conversations which is why I don't talk to my mother much often because of her. I've been told to accept it because it's "part of the family activities." I really want to be close to my mother but whenever I attempt to talk to her, I've noticed that she doesn't reply as much as she does to my sister.
<bot>: my sister and I do not get along with each other at all. She complains, interrupts my conversations and has negativity around her. I think she's the cause for my poor relationship with my mother.
