Hello @Astra lovely to meet you, welcome to the forums. You've come to a place where there is a lot of support and hopefully you will find it a safe and healing place as I have.
I too am a daughter of a narcissistic mother, and growing up with such toxicity and the early childhood trauma totally crapped on every friend & relationship I've ever had in my life too, so I can identify with you there.
Have you read the book by Karyl McBride called Will I Ever Be Good Enough?
Will I Ever Be Good Enough? Healing the Daughter's of Narcissistic Mothers
I highly recommend it, it is written specifically for daughters of narcissistic mothers and is extremely informative. My therapist recommended it to me and reading it was a revelation. I finally felt like I wasn't alone in how I felt.
You mention BPD, so I'm guessing that was your diagnosis? I'll tag in another member @BPDSurvivor who may be able to relate and help you navigate the BPD waters.
I have bipolar and c-ptsd, and of course I'm happy to support you in anyway I can with regards to having a Narc mum.
Welcome again to the forums, feel free to share your story in the Our Stories Thread
Take care and just sing out if you need help navigating the forums. You can tag me in by putting in an @bipolarbunny xx
