Discouraging..

Well ladies my husband and I have been ttc since august. I am a type 1 diabetic so I already knew that this would be tricky so I have worked so hard to keep my a1c down and blood sugar levels down.. Now it seems everyone around me is getting pregnant and some of them weren't even trying. Any advice on how to keep positive? I am so happy for my friends but at the same time your secretly wishing it were you!
