I don't know what I want from this post, maybe just to get it out. Sorry if it's long.
My family is messed up. I live with my DM, DF, Dsis and DD. I have a DB, but he lives abroad (we have a good, if distant, relationship).
DD and I have lived there for 3 years since I left her EA father, and I am saving for a house deposit. I am unable to rent as I am in London and the rents are extortionate. I do not earn enough to cover rent/bills on my own, but earn JUST over the threshold for tax credits etc. Basically I am trapped in my parent's home until I can afford (a much cheaper than rent) mortgage.
My DF has had depression for as long as I can remember. He refuses to do anything about it. I think he saw a doctor for 10 minutes around 15 years ago, never taken any medication. We grew up with him being volatile, arguments with my DM, short tempered, throwing dinner up the wall etc. He cannot take any kind of criticism (however well-meaning or innocent) and flies into a rage, followed by days of sulking and not talking to anyone. Everyone walks on eggshells around him constantly.
My DSis is the youngest, and mirrors my DF. She doesn't have depression, but as the youngest has always gotten away with bad behaviour and this has followed into adulthood. She is now early 20's. She is very angry. She is lazy and rude. Treats my DM like her personal slave. My DM collects her dirty plates and laundry from her bedroom floor. If she didn't, my sister would rage about her clothes not being washed and ready as she needs them. She is spoilt and ungrateful. She will not help anyone, she has never had a boyfriend as she sees most people as beneath her.
Last night, my sister verbally abused me in front of my DD AGAIN.
DD was having a tantrum about going to bed. Nothing major, but hey, she is 5, it happens sometimes. DD is actually a really good kid and rarely acts this way.
DSis is unwell and was resting in bed. After around 5 minutes of screaming (which I was dealing with, and DD was slowly calming down), my sister came FLYING out of her room, door slammed back against the wall, and yelled "FUCKKKK!" at the top of her voice. She came storming down the corridor to DD's room and was about to launch into a rant at DD. I calmly told her that she should go back to bed, that I was dealing with DD, shouting wouldn't help the situation and would only make it worse. (I promise that I did not shout, I said it in a normal voice. DD was already screaming, I wasn't going to add to the noise).
She just went mad. Screaming at the top of her lungs. She hates me, I'm a nasty piece of shit, I'm a little bitch, she hates me, I can fuck off and I'm a cunt. She slammed her bedroom door and I could hear her just screaming ahhhhhhhhhhhhhhhhh and slamming her wardrobe door again and again. Of course DD can hear all of this. I did not react, I walked away when she started screaming like I always do. There is no point trying to argue or reason because she does not listen and just shouts louder. DD calmed down and went to sleep after a while.
This is not a one-off, this happens on a fairly regular basis. My DM is my DF and DSis enabler, they never face any consequences after behaving this way. They aren't even challenged.
My DSis punched me in the face last year. My DM was angry at ME for not wanting to talk to her afterwards. (I would ruin Christmas, what would other people think etc). Another time, I told my DM (10 years later) that I had been raped. She only asked me if I had been drinking, no further discussion. Last night, I was told that "she is unwell, she shouldn't have done that but let's face it, you're not whiter than white, you do things wrong sometimes too. You're just as bad as each other". It always has to SOME WAY be my fault.
I'm not saying I'm perfect, I'm human, but this was in NO WAY my fault. My Sis (dropping the D) verbally abuses me again and again in this way and I can't take any more. I cried myself to sleep. My stress levels rise just by walking in the house. I HATE that my DD is exposed to this but I have no other option. I don't know what to do other than to continue to avoid everyone as much as I possibly can.
I'm sorry, there is no question or conculsion to this post, other than to say I am so so low and I don't know what to do next.
