Living with coeliac disease?

whats it like living with coeliac disease? i had a blood test done yesterday to see if i may have it.. bit scared and concerned. i couldn't imagine what it must be like to be on such a strict gluten/wheat free diet. i had a colonoscopy and the endoscopy 2years ago and i was cleared - no coeliac, crohns, colitis. he put it down to IBS. since then though i have still been feeling crook :( so he is testing me again but this blood test is more pacific. i had a blood test done before i had the endoscopy and colonoscopy. and the antibodies didn't show coeliac, but 2 of the reading where higher? i don't really understand it. my symptoms are really bad constipation, flatulence and just feeling nausea, weak, fatigued. i don't seem to gain weight - i am 21, female weigh 53kg 166cm tall. those symptoms are when i eat bread or anything with wheat or gluten i haven't eaten any wheat or gluten since yesterday lunch time it is now late in the afternoon the next day and i feel fine in the stomach. just abit hungry as i don't know what to snack on?? i have had a carrot.. and for lunch i had white rice and vegies. the doctor also suggested i stay away from fibre as that really gets me. e.g 1 uncle tobys vita brit .. it makes it really hard ..
