Dear Divorced

Just reaching out with the warmest of virtual hugs. I personally can relate to your pain so much (2 years ago my unofficially diagnosed eBPDh of 21 years had a psychotic break, raged and verbally abused me for almost 3 weeks and then assaulted me - no prior history of any of this behavior because I'd largely been idealized for most of my marriage - the cracks in the facade were confusing rather than alarming up to that point

).
I so get the feeling of being discarded like a piece of trash - it's a uniquely, horrifically painful aspect of a break up with a BPD. Everyone thinks that you are going through a "normal" divorce and that you are both relatively emotionally healthy people who just grew apart or that one of you cheated on the other. The truth, to my mind, is so much worse because it is so honestly bizarre. Your ex switched off any feelings for you like a faucet and moved on quicker than you could blink. Meanwhile you are twenty steps behind, likely still emotionally attached to your ex-partner, standing in the rubble of a marriage breakdown that you are just coming to grips with while your ex-partner is on a dopamine-high and in love with a new person. Like me, I'm guessing that you are questioning everything about yourself and reality itself. It's mind-bendingly confusing and hurtful and my heart goes out to you right now.
What saved me was my teen son, I simply had to keep on going for him and you will need to do the same for your child also. Our kids are down one parent and we have to parent for two - bluntly put. Keep posting - this community of people are nothing short of amazing and everyone just gets it to the core.
My personal recommendation would be to find a good therapist. You are at the beginning of a long road of self-discovery and peeling the onion of understanding of BPD - it will help you tremendously to have a professional help you on this journey.
Hang in there sister

Warmly,
Baglady
