Hi Producer,
I am so sorry to hear about your loss and would like to help. Many on here arrived a their lowest ebb but have now healed and live full lives. I’m one. But we would need to know a bit more about your situation. I could guess, but prefer to ask; which member of your family displayed BPD behaviour ? What immediate difficulties are you facing ?
The good news is I believe your live in a city with resource for BPD, but we would need to know more, if you are happy sharing.
