Hi Doni,
I think your fear is actually very common for emetophobes. I am scared to death of others being sick, even though I think it is because ultimately I am afraid of myself catching it. That sounds like a horribly traumatizing experience you went through. Have you ever been treated for PTSD? I have heard that in some cases, treating the cause of the emetophobia by treating the trauma that caused it can be successful along with other treatments (like GRADUAL exposure). Either way I am very sorry you are dealing with this as I know from personal experience how devastating it can be to not be able to care for your own kids.
