Does anyone else ever feel this way?

I have an ultrasound appointment bright and early in the morning to check on my PCOS and had lots of labs done that we'll be looking at. My fiancé and I are planning on trying for a baby after we're married in 4 months. We've already suffered one miscarriage, which was hard on the both of us. I feel really bad, because he's so positive about the whole infertility situation and I feel like a Debbie Downer constantly about it...and almost resent that he can be so positive. I know that sounds awful of me. Do any of you all ever feel this way?
