Hi, I'm new too. Glad to find others who understand this! Like Emmy01 I was scared to have children because of my fear, and later found that it got a bit easier. Even when DS caught a bug last winter, I was able to manage my panic somewhat and was quite chuffed that I didn't get sick. It helped that DP was not bothered by cleaning up.
Haven't been sick in nearly 30 years, so the fear is working in a strange way. But it affects what and where I eat (no take away, no curries, etc.), and sometimes where I go (no crowded shops in winter, so holiday shopping is difficult). My mum had it too, which probably explains it.
Will look into hypnotherapy. Thanks for the suggestions!
