electrolytes, electrolytes and electrolytes again! Please be careful of any straining activity. If you WANT to eat maybe try having some of your favourite ever food? It can be a snack, chocolate etc anything that you love - maybe that will help with your appetite. I’m so sorry you’re going through this
If you want to stop fasting and aren’t hungry I recommend liquid calories, like smoothies or protein shakes. You can rack up the most calories in liquid form. If that doesn’t seem appetizing, Ice Cream Shakes.
Definitely make sure you’re getting sufficient fluids. A decade ago I lost all appetite and couldn’t eat after my marriage suddenly imploded. I dropped 9 lbs in 2 weeks. I had been dieting for a while at the time, and this blew me right though a long plateau to my goal weight with no effort at all. On the 14th day I ended up in the ER with kidney stones. Looking back, I’d had a dry mouth most of that time, but I had never felt thirsty.
If you’re drinking lots of fluids and taking a multivitamin and electrolytes, you can go weeks or months without food as long as you have the fat stores to feed your body.
My condolences to you for whatever has happened to your loved one. I hope they make a speedy and full recovery and are feeling better soon.
Might not be the kind of answer you’re looking for, but having been in a similar situation I would take up meditation or prayer. You actually have enormous potential, having experienced this extreme event, to change your life profoundly, getting your mind very quiet and peaceful is the best way to move forward. Subconsciously that’s likely why you’re in a fasting state right now. Hope this is helpful.
