It's been exactly a week since I had my gallbladder removed due to stones. I sometimes feel the same or worse than before the surgery.  I can not eat without getting sick to my stomach.  I do not know what is wrong with me and I'm wondering if I should go to the ER. 

My surgery had complications.  I stop breathing for a few seconds and the doctor's brought me back to life.

Any suggestions?  Greatly appreciated
