Hang in there...a lot of us are in a similar boat, but if God gave you this Cross I am sure He knows you can carry it.
It isn't easy, but Prayer helps. If things are getting you down tell your Doc. Talk to family aswell. I know they don't always understand but it feels better talking about it.
I too mention the name of meds to my Dr that I have heard may help me. If they get all affronted then find another Dr.
Maybe see if Heather's books/dvd work for you and if they don't, try some elimination diets but do so with your Dr or a Dietician fully aware of what's going on.
Please know you are NOT alone. I will keep you in my Prayers. You must be really tough to have had this put on you.
