Remorse?

I was wondering if anyone can speak to it being normal to feel somewhat remorseful about choosing to have surgery? I'm 5 weeks post op, lost 30 pounds preop, and only 17 pounds since the surgery. Suffice it to say I'm so disappointed and am beginning to feel like this may have all been for not. Reading about everyone else's success had me hopeful that I'd be sitting pretty on the loser's bench by now, unfortunately I still feel like the fat girl that doesn't get invited to take a seat. Been in a stall for 19 days now and I've tried everything to stimulate some change. I really increased my protein for a week, I ate more calories for a few days, and now I'm on day 3 of the 5 day pouch test. The only difference I've seen is the scale shows I've actually gone up a pound or two then back down.

Today I got to eat some eggs as part of the 5 day pouch test and they felt like a rock in my stomach. So uncomfortable and made me feel more miserable than every. I can't imagine that I'll feel like this for the rest of my life when interacting with food. I don't feel like this is normal and all the happiness about my decision is starting to drain away.

Can this procedure actually not work? Can the body be so resistant to weight loss that it fights to hold on to it? Is there anyone out there who feels like they haven't made the best decision for themselves? Has anyone gone through a period like this and can speak to it actually getting better? I know it's too late and can't take it back now, but how do I live with it?
