Hi angelove79,

I'd like to join Naughty Nibbler and welcome you to bpdfamily. I think that it takes courage to set boundaries, I can relate with that anxiety. It helps to get as much as support as possible, you have found a group that can relate with you and offer you support. You're not alone.
A book that i'd like to suggest is from our review of
Stop Caretaking the Borderline or Narcissist It's a self help book on how to change the dynamics of a r/s with a pwBPD and move it in a healthier direction for yourself and to stop worrying about a pwBPD's needs.
