Is anyone else’s on the fence due to the possibility of having a special needs child?

So I am 26f and on the fence about having a child. For context I have. Brother who is autistic and also has epilepsy and adhd. Depression, cancer, and kidney disease runs in my family. My bf’s family had a history of severe depression, adhd, and bi polar disorder. If I’m being honest if I had a child there is a HIGH chance that my child with have these issues.

That being said, I would like to be a mom but I have absolutely no desire to be a mom of a special needs child. My parents are going to be caregivers for the rest of their lives and I see how hard that is. I’m just terrified that I will have a child who is special needs or has medical issues. And for that reason I am very much so on the fence.

Is there anyone else who fees this way?
