I am 27 and have been in therapy for my disorder for roughly 7 months. I am learning a lot and slowly taking control of my emotions now, but how on earth do I handle spending days around another Borderline who denies her illness?

My sister is where I was a couple years ago but refuses to see it and it is a huge trigger for me.

I am stuck out of province at her house just after a huge fight between her and I and I dont know what to do.

(Sorry for grammar)
