Trying to keep my shit together at a wedding

My husband and I unfortunately had a MMC back in April and on the day of my d&c; close friends of ours told us they were expecting and had the same due date 😭 we're so happy for them but it just was difficult for us to deal with. We're all at a wedding tonight and there is so much talk of the baby. like I say.. we are so happy for them but it is killing me a little 😭😭😭😭
