17 is such a hard age

Have you read Blaise Aguirre's book BPD in Adolescence? That book was a huge eye opener for me in a general sense. And from there I discovered Loving Someone with BPD by Shari Manning. I also found I Don't Have to Make Everything All Better by the Lundstroms to be excellent. One thing I found with BPD is the need to a) validate feelings while b) making them accountable and doing that in c) a simple way. The best way to do that, in my experience, is to ask validating questions. I have all but stopped giving advice and went light as a fairy in my approach, not just to be 23-year-old BPD daughter but to my 18-year-old son with Asperger's.
What are some of the things you are finding most challenging at the moment?
