Sister in law gave birth 3 months after my loss

Today I woke up thinking I was going to deal with the fact that it’s been 3 months exactly since I lost my girl at 39 weeks. But instead I wake with a photo from my brother that my sister in law has given birth on the date she was born 3 months ago. It’s hard to be happy fully because I can’t help but think why did they get their baby girl but I didn’t get mine. They were supposed to grow up together. It’s just not fair.. now my baby and my birth will be forgotten because she brought life into the world and that’s more important to others.
