Am I a terrible person? 😥

Am I the only one who is terrified of giving birth to a baby with disabilities? I would probably hate myself or blame myself for creating a life that can not function on their own ... I would love my child but know there are people out there blessed with the patience to care for children and adults with disabilities. I am so afraid! I had a dream that I gave birth to a baby with mental disability and I gave them up for adoption just for the fact that they had a mental problem and I could not handle the responsibility. What is wrong with me? Why do I feel like this? 😥😞
