DH, bless your heart. I think it's perfectly normal to have new stressors due to our fried Central Nervous Systems thanks to infidelity and covid.
I have some new and misplaced anxiety issues since the A. Terrified of bridges and snakes and terribly easily startled. I went from superhero in a crisis to incapacitated in an emergency. I can't make decisions now without agony, researching the heck out of everything lest I miss an important detail and have regrets. Wonder where that came from, lol. I get the why of it, understanding intellectually that I am stressing over little things due to the chaos in my life, but hate not being in control of it. No wonder the phone stuff is stressful - they cost a fortune and we can't function without them and they are changing so fast I can't keep up. Nothing is easy since covid either, not just the going and getting, but the supply chain is a mess too. Hope you get that phone sorted out and are happy with it. Eating is another thing on its own.
When I get anxious or upset, my stomach starts to churn and make ridiculous noises, and my IB flares. I struggle to find food I want to swallow, because it gets gaggy in my throat. I had a spiral after my 4th or 5th DDay when I found out how stupid I really was, and that nervous stomach and nausea thing would not stop. I lost a little weight after the first Dday, but a year and a half out it started coming off no matter what I ate. I lost so much weight I was sure I had cancer. Went down to my 16 yo weight, and wish I could say I looked great, but I suddenly looked 10 years older due to the wrinkles and stress.. I did lots of tests, had my colonoscopy, all fine and finally made the mind body connection.
The stress in my head seems to go straight to my gut. I am queasy and don't want to eat, nothing looks appetizing, and nothing tastes good. Except salty snacks and wine, that's another story/problem. Anyway, I recognize the stomach connection, and know that if I have an argument with WH, I won't be able to eat anything. I used my fitbit to keep my heartrate under 100 by controlled breathing and mental breaks to stop the stress chemicals so I don't wreck my stomach with the stress.
Keep trying, for me oatmeal is either the yummiest or disgusting gruel depending on my mood. Toast and jam or honey or fruit smoothies with protein powder I can usually get down when I'm stressing.
Good luck sorting it out, the phone and the fridge!
ps - I run hot/cold ever since peri-meno at 43, 61 and still daily, hot cold, and yes tight in the chest too. Oddly, my chest pain is referred neck pain from Cspine herniations and bone spurs, and is aggravated by too much time hunched over a computer. Remember to stretch. The chest tightness could be indigestion, stress or any number of things. I always assumed the worst, but have learned that many of my health symptoms are are actually referred or symptoms of something else. Be well....
BW: 61 WH: 61 Both 57 on Dday. M: 34 years, 2 grown kids, 9 year Affair with MOW, 7 month False Recovery, year + trickle truth. I got rid of her. Reconciling, but the lies have piled up. Trying one more time.
Sorry for the sticky shift key and typos.
