How do you feel when others announce their pregnancy?

I just learned today that some people feel intense jealousy and wish they were in their shoes and I had to reflect and come to the conclusion that I never felt this way. I usually feel happy if they are happy but the feeling I feel is intense relief that I am NOT in their shoes. I then realized after a pregnancy scare how terrified and hopeless I feel. And with this realization I am inching closer to my conclusion, I am leaning more towards strictly childfree.

Asking you all my title question and how do you feel when/if you've had a pregnancy scare?
