trigger warning: mentions of abuse, dissociation, sex

Frankly, I feel like running away. If I had money I would fly to Philadelphia to be with my aunt.

My dad's cool behavior and angering way of speaking to me triggered me and reminded me about his psychological abuse to me. I'm scared of going to sleep because he used to tell me scary stories before going to bed.

My mom's drinking triggered me, I always get angry when my parents drink and I depersonalize/dissociate easily. Her drunken joking about my sister's boyfriend being a sexual predator (which I don't think is true. I think she just said it because theres a big age difference between them) triggered me and sent me into sobbing fits in my room for a long time until I couldn't hyperventilate any more because I was scared of passing out. The only thing going through my head was "I need to get a job and move out" which is another issue for another thread. It took me so long to calm down after that

And now my sister and her boyfriend are in the next room over, the walls paper thin, having sex. It's all causing me to think pretty harmful / unhealthy thoughts to myself and I want to get out of this place forever.
It might not seem like much to anyone, but this is a big deal for me. Even the mention of certain words trigger me and the way my family is.. I can't deal with it anymore.

Anyway, my point is, is it unreasonable to bang on the wall and tell them to stop?
I think it's really inconsiderate of my sister and her bf because her room is inbetween mine (i'm only 19) and my brothers (a 16 year old). This isn't the first time she's done this when both of us were trying to sleep. I mentioned it to my mom and she just said "I don't want to hear about it"

I kinda of want to tell my mom that if it happens again I'm going to grab a blanket and a knife for self defense and sleep somewhere else (probably a nearby church) because if I hear them again, I might get angry and say something, which can most likely cause my sister to be angry at me, which I don't want because I'm afraid of her.
