Did any one have a da vinci robotic myomectomy? iam scared to death as this my first time going under knief.?

I will have a da vinci robotic myomectomy next week, I am afraid of GA and pain and also recovery time and future pregnancy chances, 28 years, no kids.I have no known medical condition except for I am over weight and sometime a little asthma tendency, I have 3 fibroids and do not have any symptoms from those only my doc. thinks that its needed because of more chances for pregnancies, I was trying for last 3 years and did not get pregnant, my main concerns are GA risks and pain, recovery time and the length of the operation, it will take almost 4 hours and how I will feel after the surgery.
