O.K. first of all take a deep breath and relax.
I have had 2 c-sections and I agree with your Dr. that the second one is not as bad. My kids are almost 5 years apart (4 years 9 months). My first c-section with DD13 was an emergency because she was stuck because she was face up and after pushing for 4 hours she was no longer tolerating labor well. When she was born I was exhausted and a freakin mess. I was also in a massive amount of pain and I normally have a pretty high pain tolerance. DD13 was born on a Wednesday at lunchtime and I went home from the hospital on Sunday, I was still in pain and completely wiped out.
Fast forward almost 5 years later when DS9 was born. He was a planned c-section and it was a thousand times easier. I was more relaxed because it wasn't an emergency and I wasn't panicking about it. Yes, i was a bit nervous but,not like the first time. I checked into the hospital at 6am and DS9 was born at 9:19am. I was able to get out of bed that same day in the late afternoon (with DD I barely made it out of bed the next day). Sure, I was in pain but, it was much more tolerable because I wasn't exhausted. DS9 was also born on a Wednesday but, i went home on Saturday and I felt so good that we stopped at Babies r' Us on the way home(wanted to get some boy clothes).
Every labor and deliver experience is different so don't worry about it being like your first ,especially since your first was an emergency. The stress alone from having an emergency c-section makes it harder than a planned one. Good luck and congratulations!!!
Oh, by the way DD13 was stuck because her head was freakin huge! She weighed 9 and a half pounds and I think 9 of it was her head, I swear that head was the size of a cantelope! Lol
