big eating changes

i am terrified of the changes i have to make to my diet...im scared that i have no idea what i am doing...i am beginning the process of taking gluten and dairy out of my diet...im having so many stomach issues that  i will gladly do it...but its taking away a lot of stuff that i eat on a regular basis..and that is scary...i know there are a lot of gluten free options but im not big on trying new things..and for right now im going to go back to what i know and am comfortable with..as i learn more about this...diary isnt so hard as i know there is dairy free butter..i can live without milk and cheese ... but the gluten part..that one is just daunting..no bread..no processed stuff..boring old fruits and vegetables .. meats are ok to eat..seafood..but not fried..corn stuff is ok ..and im suddenly glad that i like grits...im tryin to go slow but i know i will just stop eating the stuff as much as i can..and see if it helps...
