I'm pretty sure it is this one. I've liked it a lot so far and how differently it approaches bpd.
I felt the same way. Have you tried this?
The Borderline Personality Disorder Workbook
I would suggest this workbook and this book for yourself. Then I would suggest this book for your loved ones.
Here is some good information on the different therapies for BPD that they say are most effective (DBT being one of them).
I follow a bunch of accounts on Instagram with inspirational quotes and relatable content that I find helpful. My favourite hashtag being # bpdrecovery - if you use Instagram, I highly suggest checking it out.
I think the most important thing to remember is to be active in your recovery and to be kind to yourself.
I hope this helps!
