It's not just noise for me, my wife has severe allergies, to food and smells, she has to carry a auto adrenaline injector, with another as back up. She is unsurprisingly extremely anxious around food, which manifests itself in different ways, I can literally feel and hear her anxiety, even if I'm not seeing her prepare cook and eat. I can hear it in the way she picks at her food with a knife and fork, even how she stirs her porridge, which nearly always ends up burnt, all her food is cremated because she's obsessed with bacteria.
I bought a food thermometer but she wont use it, hence everything is cooked for twice the usual cooking time, with regard to gas marks she always goes at least 2 gas marks higher, no simmering, always rapid boiling, veg turns to pulp, chicken to rock and so on. She has an eating disorder, very similar to anorexia, which I experienced first hand with one of my daughter's, who at aged 15 was sectioned to keep her alive. So, for my wife, all food is dissected (by her), the food wastage is off the scale, she will only eat frozen peas, nothing else from the freezer. A long time ago my wife nearly choked to death whilst eating ice cream, a hefty slap on the back, from me worked, I think she has an out of control gag reflex, linked to her constant all consuming anxiety.
I'm used to it all, this has been going on since 2001, when she was resuscitated three times in the ambulance, on the way to hospital, after suffering her first anaphylactic shock episode, I get where she's at.
Just a long winded way to say that any noise associated my wife's cooking, even prepping her meal, the constant boiling of the kettle, the clatterings, the vibes, her constant coughing and spluttering when eating, it rubs off on me. It was a friend who told me I had misophonia, he knew because he is a sufferer from it as well. Apart from hearing anyone whistling I don't tend to get in a rage, he does though.
Wasn't my intention to derail the thread, I think there is some relevance for me to post this message here.
