I also have BPD but honestly I think it is a trait of being a parent that you don't want your kids feeling hurt. My son is almost 13 and there are often times I just want to take all the pain away, he is on the spectrum and has so many issues that I just want to make better.
There is a book that many of my friends have recommended: Raising Your Spirited Child, Third Edition: A Guide for Parents Whose Child Is More Intense, Sensitive, Perceptive, Persistent, and Energetic
Good luck!
