I am so sorry for your pain. Thats horrible that OB would do that but it also doesn't sound uncommon unfortunately.
I am glad the milk supply issues have cleared up! Don't beat yourself up for not directly breastfeeding. i had a lot of issues and ended up exclusively pumping. I tried really hard to get dd back to the breast but it was too late by the time I seeked enough help. I hope you have more luck. Enjoy your babe!
