Surprise diagnosis of Barrett's Esophagus

Hello. I've been diagnosed with Barrett's having never experienced heartburn. I am scared and don't know where to start since I haven't been suffering from acid reflux. Scary part is I still feel nothing wrong when I eat so I don't know what not to eat...other than seemingly everything after reading about it. And even scarier is how it can progress if I don't do something. I am a 38 yr. old woman who can stand to lose some weight but  not really that problem either!  And I want to have kids. Does anyone else have this? Any advice?
