Food? Is it really necessary?

I had an insanely busy May and as a result didn't post at all.  Just too much busyness to even write at this point.
In the month of May I not only had this insane schedule but I was dealing with stomach issues. This has been going on since March but is becoming progressively worse over time. I had an endoscopy which basically is a scope that goes down your throat (you are slightly sedated) and checks out your esophagus, small intestine and stomach. My results came back with inflammation in my stomach. As the month continued on my episodes were getting worse and closer together. I told my doctor and he sent me in for a gastric emptying study. This required me to eat a radioactive egg sandwich with grape jelly. Then every hour for 4 hours they took a photo of my stomach as it was digesting. No results yet and my episodes still rage on. Since food is aggravating my problems I figure I should just go without until we get this resolved. I mean is food really necessary? I can get all my fruits, vegetables, proteins from liquids can't I? At this rate I don't even miss food because I look at it and think is eating this worth getting sick and my answer is also nope! So it's funny how at first you miss it but as time goes on you just say I don't need that and you carry on.
