Awww Aphrodite, bpd sucks WetRabidDogAss, but I promise its not the end of the world. Just this last 6 months I've made progress with my bpd in leaps and bounds, its not a hopeless sitiuation.
Its horrible to feel that your core is corrupted in some way, but bpd behaviour can be challenged, we can learn to reprogramme our default setting to a good degree. Its hard, I won't lie, in the beginning its draining to be at constant war with yourself, but it does get easier and become more natural with practice.
I'm really sorry your life has been turned upside down, the damage left behind us, bp / bpd is never pretty, but we can pick up the pieces.
I mostly post here, my family is on this board, so I keep them in the loop and that includes my bpd journey, but I do sometimes post on the bpd board when I feel its most relevent there. So don't feel that you should stop posting here or not post about your bpd here
