Rant, scream, yell, kick (soft stuff)...We are here...we are here (direct quote from Horton hears a who)...And we are listening.
You are allowed to hate it...it is not fair. And we get a truckload of unfair in our lives.
Make a list of the stuff that you can eat, add the things that you can sometimes eat or eat differently (like raw vs cooked or blended vs whole)...and see what sounds and looks good to you that way...
I know it isn't what you want to hear we have to be magicians with so little...I have learned to eat a limited diet in order to live happily...I don't like it (haven't had a good pizza in years) but I can eat whole grain pasta with a bit of parma...
I find different ways to get around things, make most of my own food (I am allergic to sulfites so anything canned or prepared is potentially dangerous) so I am learning to be creative...can't have wine anymore (anaphylaxis) so I drink grape juice mixed with bubbly water and pretend to be like others.
It is a game for me now...hubby has learned to accept a wife that chews and spits food out (can't swallow anything with fiber like pineapple or leeks or watermelon)...sometimes it works and sometimes I curse life like a trucker.
My heart goes out to you.
