We always assume the worse but genetic counseling isn't necessarily a reason to panic. It is better to wait until you know all of the facts than to assume it's bad news. I understand you're concern but thinking logically will offer better results than thinking emotionally every time. Calm down and do your best to understand what the counselor says.
