Hi Delilah123
Thanks for introducing yourself!

Your sister was diagnosed many years ago. What would you say are her most problematic or disturbing behaviors? Has she as far as you know ever gotten any targeted treatment or therapy for her BPD?
It's unfortunate though she's in denial of her diagnosis. The rest of your family is too you say, why do you think that is? Do you feel they don't agree with the diagnosis or more that they want to pretend it isn't so?
I recently went away to college and many nights this past year night were spent in bed crying and or having anxiety attacks. I didn't know why. Eventually I was having suicidal thoughts and I got myself therapy because I know how precious life is and I wanted to fight it.
In therapy I ended up discovering that a lot of my deep troubles and problems have to do with things that happened in my household. The fighting, the yelling, the crying, the raging, the blaming, the belittling. I felt like it was all my fault.
I am very sorry that you've had so many struggles. It is the sad reality for many of us that as a result of our problematic childhood, we end up with some issues of our own. It is very positive though that you got help in the form of therapy. Are those suicidal thoughts a thing of the past now?
I just needed to tell someone how terrible I feel about making my mom cry like that.
It's clear that the stress of dealing with BPD family-members has also taken its toll on your mother. I understand why seeing your mother like this would also make you upset. I do want to say though that you aren't responsible for the way she feels or how she reacts to you.
Take care and welcome to bpdfamily
