Hi fightorflight,
That is horrible news to hear about your sister in law. Do you know how she's doing now?
It's a very sad aspect of BPD that some people with this disorder struggle with suicidal ideation and in some cases make actual suicide attempts. Do you know if this is the first time she has made a suicide attempt?
We spoke with her parents today to see what we can do. Her mum said that the fractured relationship she has with me and my husband is a major contributor to how my SIL is feeling. How do I not feel guilty or responsible for what has happened?
I can imagine that her mum is also really struggling with all of this. At the same time, I also want to say that you most definitely aren't responsible for the feelings and actions of your SIL. Her feelings and actions stem from a disordered mind and you are not the cause of her disorder.
While I have some compassion for her situation and have tried to understand BPD as best I can, I have no desire to have a relationship of any kind with her. There has been so much hurt in the past. But if it's making her feel so low that she wants to take her own life, what do I do? Being a part of her life and trying to have positive interactions with her doesn't seem to help anyway.
As hard as it may be, especially since other people are guilt-tripping you, I think protecting yourself and your own well-being is most important here. You can't save your SIL or make her feel better, if she doesn't want to change herself. Although she is disordered, she is still an adult and as an adult responsible for her own actions.
I hope you are feeling somewhat better today
