New, uBPD sister moved back home

[blueberry123]

Im new here so hello!
I don't really know where to start but I just stumbled across this website after searching for help on how to deal with my sister, Undiagnosed BPD. she is 27 and moved back home during coven. I was dreading this because of how awful living with her in the past has been. It has only gotten worse. I read some posts and I feel as if this will be a safe space for me. It already has made me feel better just knowing that my family is not the only family going through this.
