Bander that doesn't feel anything!

Well, I had my surgery back in Feb of this year. I have had it filled alot and now at the 7CC mark. I just don't feel full no matter what I eat. I don't drink during meals. I am hardly thirsty since that symptom went away as I have Diabetes. I did get to the 10CC point but my stomach swelled so he took out 3CC's. I feel ashamed that I can't get under 300 pounds. My top was 330. I am also ashamed to go back to my surgeon because I don't want to know what the outcome would be, if any. It's sad too because there is no food in the house here {my family and I are a bit poor} yet I can't seem to lose and I hardly eat! I have been sweating alot during these summer days but it doesn't seem to phase. What could be wrong? Thanks for any help.
