I understand this. There is a big difference between knowing and understanding something on an intellectual and believing something on an emotional level. The work we do on the emotional level is what allows us to change our image of Self and begin to believe we are worth far more than what abusive people give us and what we accept whether it be in the name of love, family or friendship. That is when the most important change and healing begins.
Thank you for your reply, what you said is key information for all involved with a family member with BPD, and for the person who is afflicted with BPD.
