12 months and counting

I've just come back from a weeks holiday with the hubby in Australia to find a letter from Fertility Associates advising us that we had been accepted onto their wait list for public funded treatment.  We've got approximately 12 months to wait, give or take 3 months.  It was a very nice thing to come home to I can say.  My problem is or was damaged fallopian tubes, which resulted in one miscarriage and 1 ectopic pregnancy with my husband.  I am both excited and scared about this.  Even though our pregnancy will be planned I do still worry if we're ready and if we'll be good parents.  I think we'll do ok.  As I'm writing this the other half is playing, rolling around on the floor with lazy lab.  It's normal to worry though isn't it?
