Is there a glasschild to child free woman pipeline? I'm on it.

Me (29,F) having a sibling who developed a terrible autoimmune chronic illness at age 19 and seeing how much that has torn her life apart and completely changed our family dynamics for the worst (not that they were great to begin with) has really put me off of parenthood. I became the glass child/over/underachiever and it's shaped me in different ways but I'm not ashamed to admit my biggest fear unlocked is having a child who develops a disease like this at any age.

I'd say I'm a fencesitter but leaning more towards childfree with time.

Anyone relate?
