Lost one twin at 24w

I am 25w today and just found out yesterday we lost one of our twins. He/she only had a 5% chance of survival due to fluid in body. Had an ultrasound the 5th and there was still a heartbeat so somewhere between then and yesterday the little fighter gave up. Has anyone else had this happen? If so will the other twin be okay? I was so excited to be a twin mom and now I’m just heartbroken. 😔💔
