Listen. At least go to the consult and see what the Dr says. Tell them you have these worries and thoughts. They may have advice or tell you it's totally normal to feel that way! My Dr told me that even if you gain back your weight, you most likely will never gain it ALL back so at least that's a bit comforting. And when I went and had my psych evaluation and everything I found out I had binge eating disorder so they made me do group therapy for 8 weeks before I could continue with the program. Plus having PCOS he said weight gain and holding onto the weight and not losing easily is part of that so I knew I needed extra help. And im looking at this surgery as something to help me, knowing full well so much will still be on me to do things right. Doesn't hurt to have some help.
