Scared to announce

Last year i lost our baby boy at 18 wks gestation. Went in and no hb. No signs of a mc and no answers to what happened when all testing and previous scans were great. I am 11 wks today and to be honest i am scared to announce, scared to get attached and next week i will know gender but a part of me doesnt want to know. Last yr was total shock. The worst is telling your kids they arent getting a baby brother, leaving the hospital with no baby, and coming home to a room full of baby things that most couldnt be returned. He was suppose to be the last pc to our family. I thought having another baby would help me heal and be happy but now i just feel guilty. 😔😭
