How is your mum today @Dunnoburt ? And how are you?
I've been emetophobic since I was child and for periods on my life it's been debilitating (forgoing travel as I'm too afraid to be on a plane incase someone is sick, forgoing events and nights out as I'm worried about travel sickness / someone getting too drunk and being sick). My emetophobia also manifests in others being sick and I just have a heightened awareness about it. 9 times out of 10 it doesn't come to fruition but sometimes it does and then it's in my brain. I remember a car pulling up suddenly and someone opening the door and vomiting and now 20 years later I still panic if a car pulls up somewhere suddenly!. My behaviour is dictated by my phobia in so many little ways. I don't go into places with just one exit / entrance if I can help it. I wait outside of the Dr surgery if ever I have an appointment and ask them to call me when I need to come in. I avoid anyone who has been sick, I have got off trains and tubes before my stop if someone looked a bit "peaky". The list is endless really.
I've managed to have 3 DC and my DP always used to deal with the sickness bugs. Although it doesn't always work like that? I do actually find the exposure over 3 DC / 12 years has helped me. And I did have some NHS exposure therapy just before covid.... although it was never completed and I never fully knew the end game (but my sessions took place in a Dr surgery so I was expecting someone to be fake sick in the waiting room or something like that)
I am much better now. Not anywhere near cured but I able to cope in situations that would have previously had me in flight mode (traveling alone with 3 DC for example! In fact I take the children away by myself a few times a year which is something I would have never been able to do a decade ago in case of them was travel sick or ill whilst I was on my own with them)
We had a particularly hard time in the summer with 2 out of 3 children have Norovirus and DP wasn't here. DC2 was sick / trying to be sick every 20 minutes for 8 hours. In the end I was absolutely numb to it!! I do always get that horrible feeling in the pit of my stomach when I hear the dreaded "I feel sick" (or any variation there of - tummy ache / even feeling tired or looking pale sets me on edge!!). The anticipation is worse for me.
I also have cleaning rituals and anytime one of the kids has sickness I bleach remote controls, devices, light switches, door handles, keys. Things I am convinced spread the lergie. We've never all come down with the same sickness at the same time touch wood so I keep to my ritual. I actually have a hospital grade cleaning product that kills Noro and CDiff and other nasties as well.
I totally get it. I can help my DC but I still panic with other adults. I'd be an absolute last resort to look after a poorly relative. I'd clean, I'd wash, I'd go out for medicine and supplies but I'd only be with the person if I absolutely had to.
