i think my sister hates me
i am f25 and my sister f21 makes me feel awful about myself. We have a bit of a broken family and it’s just my mum, two sisters and I now. The sister in question is the youngest, I am the eldest, and she has no communication with our father. She has been hostile with me for maybe a decade now, and to begin with i could understand as i had my own problems and she was a teenager, but now i don’t know why. She is very much 3 vs 1 where she tries to recruit my other sister into her side, which is actually putting a strain on our relationship. She constantly says i smell to the point she rolls the windows down in the car if im there and puts her head out the window. this has never been a problem before, in fact i over compensate with manically applying perfume and gum. It has given me crippling insecurity about this. She only ever complains about me, makes disgusting faces when i enter the room and makes me feel like the worst person to ever exist. I have just gotten into a new relationship and this is starting to cause insecurity in that as i now believe what she says. it’s now reached a point where my entire family is going away for her birthday trip and she doesn’t want me there so i am not invited. I don’t really know how that is expected to make me feel but i genuinely am not happy in this dynamic anymore and don’t know where to go from here. I try to have as little contact as possible with her although she is currently home for a few weeks and I feel the need to hide away in my own house.
I have always been accused of being my mums favourite and i feel like that might have part to do with it? but she’s trying to turn my other sister against me and whenever we are a three it’s 2 vs 1 where everything is just a dig at me (a little bit of banter i can understand but this is to the point i leave the room really upset) What do i do and has anybody experienced this before? I don’t know what i’ve done wrong.
