Hi Buddha2014. I am new to this forum and very recently diagnosed BPII.
A few years ago I saw a Buddhist psychotherapist for help with depressed detachment and social anxiety. She was a fascinating woman with a PHD in how meditation can help cancer sufferers with pain management. Her services in psychotherapy and pain management were available on our government funded medicare (I'm in Aus), which seemed to lend some extra credibility as I was skeptical at the time. I learned meditation, mindfulness, and an entirely new way of looking at life and credit these things with a dramatic and long lasting improvement in my symptoms. I don't follow the religion but like the principles and would one day like to learn more.
I also recently started practising Kundalini Yoga which has been immensely calming and energising at the same time. If you've not heard of it - it is the most ancient yoga practice which aims to raise kundalini energy in the body whilst remaining firmly grounded. Perfect for BP in my opinion. Plenty of chanting also

I can only describe the feeling after a session as like having had a calmative and had my brain bathed in spring water. Beautiful and it lasts for days!
I believe there's much to be gained from learning Eastern spiritual teachings and practices and wish you all the best with it.
