How am I actually feeling? What am I feeling?

When people see me, they know I don't have much longer time before my due date and they always ask me:
"how are you feeling?" (with a painful face, expecting I am feeling that way).
I reply:
"I am feeling great" (they look very surprised...)
Then they ask:
"what are you feeling? Are you nervous?" (another painful face tweak)
I respond:
"I am excited, I can't wait to meet our little one..." (they -another surprised face!)

Well, I am indeed super excited and I am really looking forward to being a mother and to building a family with Jason! I know it will not be easy, but I am sure it is so worth it! I have always wanted to be a mom -since I was little and saw my younger brother and sister as babies. Jason and I waited a couple of years and actually hinted to some people we might not ever be parents... I think we were just a bit afraid of a big change in our lives! (which it will be) But I am 100% sure that we are ready for this and that it will be great!
I think at the moment, my biggest fear is the health of our baby! (they don't do that many test here in the UK) I want him/her to be born healthy and thrive in life! I have no doubt we will do everything we can to make his/her life wonderful as I have no doubt we will do our best in being parents! And I know there will be moments that we make mistakes (we are humans) but I know that we will be a happy family!
Well, this is my last week of work. I am curious to see how easily I will 'switch off'. After the baby arrives, I know I'll have my hands full.. but until I go into labor....
