Oh Lady Frog, I feel for you. Yes your guts are what they are. Like you, I'd like mine to be normal or more in line with what others experience. Sometimes it helps if you're around people with similar issues. I've always wanted to find a support group in my area but could never find one. A real in person live one but the most support I've been able to find is over the internet. In forums like this one.
As far as getting out of the mess you've "made", similar to eating foods in moderation that irritate us, try adding more food groups to your diet, but again, in moderation. It sounds as if you need protein. Would hard boiled eggs bother you? Sometimes I just cook half a dozen and keep them in a bowl in the fridge. Also, tuna salad on Club crackers tastes so good. Again, protein.
I wish I had the magic answer for you but I don't.
Sometimes I wish I could just take my guts out of my body and have them work outside of me. I know that makes no sense but inside of me, they heave, they roll, they cooperate or they revolt.
But my guts are never normal either. I've been going thru all of this for 9 years now.....going on 10, next April. I had it so good at one time and didn't even know it.
Hang in there.....hoping you receive concrete, positive feedback. I think you will.
