my best friend

So I've been friends with this girl since elementary school and I recently got married and moved away. She has always been the wild child and me? The down to earth one. Me and my husband have been trying to get pregnant for 5 months and haven't been successful. She just called and told me she was pregnant. I want to be happy for her but I'm sad and upset because she never wanted kids. I know I'm being selfish but it still hurts. I don't feel like I have anyone to talk to so I just needed to vent and maybe get some advice...😩😞
