Hey Jas! Don't be nervous. The surgery will go very well, so don't worry about that. The recovery is not fun, I'll admit, but it's not too horrible either. Follow Dawn's advice - take your pain meds on schedule. It's easier to keep the pain down than it is to catch up with it once it starts. And take stool softeners - like Miralax, which has a very good reputation among the boardies here - but you should use whatever works for you.
Everything will go brilliantly and when the surgery is over, you will be on your way to healing and getting past all this! Think about how wonderful life is going to be when you are healed. We will be here to support and advise you - you're not alone.
