I completely understand! I had my surgery back in February and I've lost a little over 100lbs. Like logically I know that I should be ecstatic and feeling on top of the world, but I am quite depressed and have anxiety. I NEVER thought that I would feel this way afterwards. It sounds silly, but I think I was more comfortable with the old me, then the new me. Most of the time, I can't stand to look at my body. I feel like it looks like everything is melting. I exercise, but I still have extra skin (which I knew was normal before surgery, but to actually have it happen is a whole different story) and my boobs are basically gone, lol.
Another weird thing is that when I look in the mirror, I see my old body still. I don't see the smaller me, so I end up getting upset - thinking that I'm not doing enough. I talked to my family doctor about this the other day and she said it's actually common after the surgery. She's referring me to a psych that specializes in eating disorders/body image and depression (and we upped by anti-depressant). So...hopefully it'll get better. I'm hopeful that it will. I think that things just happen so fast physically, that it just doesn't give us enough time to adjust mentally, you know. Good luck to you and I hope things get better!! Thanks for sharing your story!
