You are normal I promise. Honestly I probably cried every single day of my liquid only phase. I did not have buyers remorse I just felt plain left out. Now that I can eat some mushies I am doing much better.
If you feel you need professional help don't feel dumb or embarrassed about getting some. You have lost a huge crutch you have used for years to get through tough times. This is a major lifestyle change. What we go through before, during, and after surgery can't be discounted.
You are strong! Stay out of food situations. I had to stay out of grocery stores and ignore signs for food, looking the other way. You can do this just don't torture yourself by being in those areas.
