My history - XH (married to him for 20 years, emotionally abusive hence the X bit) was a martyr to his stomach. We would symptom watch almost every night. He would also symptom watch the DC. If anyone did get something, it was my fault because I was the one providing the food and keeping the house clean (or clearly not keeping it clean, if we were ill).
This means that - even 7 years post-divorce, after some CBT and hypnotherapy - I still react to anyone (family, stranger, colleague) saying that their stomach feels unsettled etc. I'm better if I don't know. As soon as I know, I fret until I'm feeling queasy myself.
So, I'm trying to get some perspective. Last night DP was up once in the night with a single bout of the runs for no apparent reason. We hadn't eaten exactly the same things yesterday, but we had mostly and I was fine (apart from the panic that DP would consider it my responsibility that he was ill... he is not in any way like XH at all, but this is still where my brain takes me). I spent some time between this 2am event and finally getting back to sleep, waiting for him either to be sick or for me to be sick (my biggest fear of all). Incidentally, neither of us was sick and he is fine this morning.
If you have no underlying health issues, how often does your stomach not feel quite right? Can anyone help me with perspective?
