Thank you for posting a follow-up I was very worried about you when you posted and I'm glad you are OK. Yes, there can be life-threatening complication from Gallstones and sometimes it is just too late to save the gallbladder. You did try and it just wasn't meant to be. I think you did the right thing and will be OK & heal quickly, easily and well -- just keep eating healthy (you need your strength) and get plenty of rest and keep thinking positively! I think visualization is great for healing, visualize your incisions healing and the energy flowing through -- you can also try some hands-on healing.
I also wanted to add that when you posted my intuition say "pancreatitis" and "hospital" very strongly, otherwise I normally never try to convince anyone to do anything here -- I'm here to learn more than advise.
Pregnancy does weird things to women's bodies and the effects of it can cause mild conditions to become serious very quickly. There are many stories of people being very healthy after gb surgery and living long lives and may you be one of them. :)
