I can completely relate. The only thing that happens when I adopt such a strict diet is that I lose so much weight that I get even sicker. Not to mention my Depression goes thru the roof and I get extremely constipated. :-( Not fun.
I wish there was a set protocol for this. Too many theories abound and NONE seem to work all that well. I envy the people who can eat whatever they want and can live a pain-free/symptom-free life. To be able to grab an ice cream cone on a date, eat a pizza while watching a football game at home, or to go to a restaurant and not have to be worried that you'll "pay" for it later... it's the simple things I miss. I hate having to wake up 2 hours earlier than most people just to make it out the door at a decent hour due to the fact that I'm in the bathroom that long. I hate having to change my clothes in the afternoon b/c I get so bloated and uncomfortable. And I hate being underweight and having the body of a 12 year old, despite being twice that age. I hate how my health has deteriorated to the point that I cannot work or go to school and that I am now on disability. I hate being a burden to my family, not having friends, and feeling like I exist instead of live.
Sorry for the rant....I get down sometimes because this all feels so hopeless.... :-(
