Is being both borderline and c-ptsd going to be harder to manage as I?
Read that to yourself again and I think you can come up with the answer yourself. Seriously though, of course its going to be difficult. And judging by the way you worded the question, you already knew that. BPD is a bitch, c-ptsd is a bitch, being in a relationship with an abusive narc is beyond horrible, and having no safe place to comfort you and make everything easier to manage is horrendous. The most advice I can give you is to please seek help. Get out of that toxic relationship, and focus on yourself and bettering your life. Youre not going to make any improvements if you ask strangers on the internet questions you already know the answers to.
