Afraid to eat outside my house

I am newly diagnosed, about 6 or 7 weeks now. I originally came down with what I thought was the flu, but after 9 days in the hospital, my doctors said I have celiac disease. I have been doing om he at home because I have always been the main cook in my family. Changing my diet is not a big deal. I have been feeling much better and feel in control. My question is, how do I give up control and eat at a restaurant? I have downloaded Find me gluten-free, and looked at the app. I'm really apprehensive about trusting restaurants. I have not had any gluten since I got out of the hospital, so I don't know what will happen to me if I try it. I was so sick for a month that I didn't want to go back there, so for the time being, I have stayed home and prepared my own meals.
