Hi, I think you were lucky to have two people with your mother during and after the surgery. Anything can happen during surgeries (bp going up/down). Its good to have trustworthy,genuine and caring people to be around during surgeries, particularly since you have health issues like fainting previously. A friend of mine went for c sec, her bp rose, she suffered an attack, was in icu and gained consciousness only after 3 days. Thankfully nothing bad happened and you could control things except for the 1 incident with your friend. How did your ex react when the friend instructed to be in your room. Looks like you care for others emotions and cant spontaneously say no to things that disturb you.
