1 year without my child and thoughts of having another

Its been one year since the loss of my child on June 17. We did release lanterns and balloons for her on her birthday June 9th. I have an extreme empty feeling. Lately I've wanted to have another baby really bad. I know I can never replace my daughter and I would never ever try to but I'm not sure why I want to have another baby so bad. Now my child passed due to a hospital overdosing her. She did have the same terminal illness I have and I fear the next baby will too. I know what to do more now but it doesn't take away watching your child stop breathing and heart stop multiple times in 2 years. I don't know how long I have left to live and I have no idea how long my child would've lived if the hospital didn't mess up. I don't know how I will be able to handle doing it over again with my ptsd from watching my child die over and over again. I would really appreciate your guys thoughts on it. I'm lost
