I can relate 100% to the original post. I get dressed and things dont feel tight or they seem to contour in a good way then I feel great! And as soon as I see myself in a picture I feel embarassed for simply being me. For being my size, for thinking I looked alright. I get down on myself when I see photos its like "wow you really felt confident leaving the house like that? better think again" and it works into this depression thing that just makes you feel like giving up at times.
I've been gaining weight for years since high school, and I still view myself as the same size.. when I'm very clearly not. Gotta get that into perspective to move forward =)
