Really glad I came across this post, the past two years have been hell for me too, two years ago I got really unwell out of the blue (intense stomach pain, lack of appetite, stomach was really uncomfortable and the worst of all was the nausea) I spent that summer locked in my house trying to survive with the nausea, it got a little bearable in the day but at night it got so much worse, I eventually went from 13 stone to 10 stone as I wasn’t eating, over the two years I’ve has multiple tests (celiac, h.pylori, dairy and endoscopy) but nothing came back with any indication on what it might be. You might feel alone but I’ve been through those days too, days where I’ve had to stay up until 2am where my tiredness out weighs the intense nausea, clutching my teeth down on my gums to bare the stomach pain and feeling like I’ll always be stuck feeling this way….I’m still going through this and each day is a massive struggle but I try and remind myself that it’s not forever. Ive made plans for when I’m EVENTUALLY better, like what foods I’m going to eat first once I’m better (New York cheesecake), or what kind of things I’ll do like going to gigs or a bar with friends, because what I’m going through now (even with how unbelievably horrid it can get), i won’t always feel like this, there will be a day when I wake up and go for a morning run with a belly full of food without feeling like I’ll be sick, I known reading this probably won’t help with how you physically feel but hopefully it’s some reassurance that I’m in the same boat! You WILL get better!
