My sister is mean and scares me, what should I do?

[Lubbock47]

My sister is 2 years older than me and has a personality disorder (borderline). She never really liked me, but it got worse over the years. I will be more or less alright for a couple of months and then she would find a reason to scream at me, run after me or just make a hurtful comment. Then my mother would explain her behaviour with her disorder and ask me to give her another chance. This has happened over and over again. For months, she has been sighing really loudly each time she sees me and when my mom talks to me she does everything to get my mom to go to see her instead. A couple of months ago, she hit me with a wooden spoon without me doing anything to deserve that. After that I decided to stop trying to have a good relationship with her cause it didn't help anyway and it was just draining me mentally. We haven't really spoken since that incident. Today, I was preparing to leave for school and I scared her cause she didn't know I was coming around the corner. She screamed at me so I screamed back and then she wanted to force me to talk to her. I repeated over and over again: I don't want to talk to you. I don't want to talk to her without my mom around cause she acts impulsively and scares me. So I ran back upstairs to calm down a bit, but had to go back down cause I had to go to school. When I went to put on my shoes she followed me and cornered me. She took my second shoe away and was shouting at me to why I wouldn't talk to her and that I was ruining everything. I told her to back off, but she didn't seem to understand and cornered me even more instead. I decided to take my boots and to run for it, which she really didn't like: she yelled that she hated me over and over again. I really don't know what to do anymore. It's really exhausting. I would like to move out, but I'm not financially stable enough. Do you guys have any tips on what to do?

living with a BPD person is extremely difficult. if you can, please find somewhere else to live (a friend that can take you in?). she HAS to go to therapy to learn how to deal with BPD as it's not curable... she has to work through it. and i truly hope she is seeing a therapist because it can be dangerous to go without if you have BPD.

in the meantime, if nothing else is working, you'll have to try your best to avoid her and be outside of the house if she's there. but that can really disrupt your life, but it's better than dealing with the effects of someone like that.

She is mental ill, don't expect reasonable behavior from a borderliner. Avoid her as much as you can and if she starts to provoke or insult you, just think she can't control those negative impulses, forget and don't take seriously what she said.

By any chance is she looking for a guy to date/serve her?

This sounds horrible! You have no support, right? Maybe you can live with a friend or relative? I'm sorry you are going through this. It definitely sounds scary. I hope you are okay 👍

She’s jealous of you.
