I have HPD and its a hard thing to cope with....when you finaily realize you do what you do, for love and attention, from anyone, the lying is a coping mechanism to seem more improtant, becasue you feel empty without the approval from someone else, the need for appreatation is the main thing, i started acting out about that age as well, 14 now Im 35, been therapy for years, was misdiagnosed for years, but good luck
