SIL has baby early

Well I was planning on being out of town when my SIL had her baby just so I could avoid the craziness. She had her baby yesterday. I don’t know how to deal with it. I know my husband is going to want to go see her and the baby but we have a bad relationship and I don’t know if I can handle it. I just wish I wasn’t so crazy these days and that I could be happy for her. I start my 5th round of Clomid and see no end in sight for the pain
