Help and advice please

I have severe debilitating chrohns disease. Its a bowel disease with no cure. I am concidering to completely change my diet to vegan to see if it benifets me from cutting out everything such as wheat , gluten, dairy, yeast, additives, oils, etc. Has anyone with chrohns on a vegan diet gone into remission?? I am not lactose intolerant, celiac or have suger intolerances as i've had the tests with negative results including camera down my throat. Anyone been very poorly and got much better on a vegan diet ?? Many thanks for replies and advice.
