one of my best friends is pregnant

I was on Lupron for 8 months because of my endo and now my husband and I have been trying for 4 months with no luck. A few months ago one of my close friends found out that she was pregnant. When she told me she said she wish she hadn't gotten pregnant. She is keeping the baby but still brings up wishing it hadn't happened. And if that isn't hurtful enough for someone TTC, we were eating lunch together and she tells me how cute all my baby nursery ideas are and basically stole them. Now she is doing his nursery how I'd planned to do ours when the time came. I'm so annoyed and frustrated.
