Make sure you're not drinking your calories (sweet tea, sugar loaded coffee, carb-loaded drinks from Starbucks, etc) & make sure you are getting enough calories & protein. Do you track your intake on MyFitnessPal or a similar website? Are you measuring your portions? Are you drinking while eating (instead of waiting 30 minutes before & after eating)? Go back to basics to reset your way of thinking & eating. It might be wise to start back with liquids only & then progress through the stages (clear liquids with protein powder added in), then full liquids, pureeds, then soft foods. This might help to refocus your thinking about portion sizes, etc.
