My best friend is pregnant after 2 miscarriages (so so happy for her!!)

Yesterday she found out the gender and that baby is doing great!! She's coming over tomorrow with her husband to tell us what they are having and show me some things for the baby and I'm excited but honestly today I'm emotionally drained just thinking about it. I've suffered one miscarriage myself and infertility for a year and a half we've been ttc. She's supportive of my situation and knows my struggles but says stuff like "I always thought we would be pregnant together" Advice for sharing in a friends happiness and putting my bad attitude aside? (sorry for long post) Thanks everyone ❤
