Glad your little one has perked up and hopefully noone else comes down with it.
Anticipation is the worst part of the phobia for me.
I find I can deal with actual vomit but waiting for someone to be ill, just kills me.
I find myself on heightened alert, so for example if one of the kids is tired or doesn't feel hungry, I assume they have a sickness bug and watch them like a hawk. I'm careful to disguise it as best I can as they are a bit older now and I don't want to pass this down to them.
If one of them complains of actually feeling sick then I'm just a mess. I feel like I'm waiting to be shot.
It's sometimes exhausting to live this way and my life is quite severely affected. I haven't travelled on a plane since 2014 for example (fear of being trapped with someone who is travel sick is just too overwhelming). Although we do manage UK holidays / train travel.
I avoid car travel as much as possible (we don't have a car...living centrally / prohibitive cost is the main reason but my phobia plays a part)
In my youngest years I'd never use the Tube at the weekend after a certain time (and I'd never use night buses) due to drunken people being more likely to vomit.
I am always more alert to cars pulling up suddenly (someone once pulled up, opened door and puked)
I always feel anxious and tense when I hear there is a sickness bug going around. Especially if we've been around anyone who has been sick.
I wait outside when we go the GP.
I have been to A&E with my DC a few times and I'm usually an utter mess and end up outside, leaving DP inside. Ironically we had to take DC1 in when he was 4 as he was severely dehydrated followed a sickness bug. DP took him in as I couldn't. When we knew he DC was being admitted then we swapped and I stayed with my DC. He'd had anti-emetics by then.
There are many other examples, I feel like I run on a different frequency sometimes.
I have long periods of functioning well but I know this isn't "normal". I was 3 or 4 sessions into exposure therapy when Covid hit and I was discharged when f2f therapy couldn't continue. I have no idea where this therapy was going to end (it was set in a GP surgery, I always suspected I'd have to deal with a fake illness situation?? I never asked) but I need to revisit therapy.
Oddly enough I'm fascinated with hearing stories about people's illnesses things like breakouts on cruise ships. I find it almost comforting that if XYZ happened to so and so, its unlikely the same would happen to me?
