A little late to the party, and going to get buried, but here it goes.
Even though you know that there are a lot of people that do not care, or judge you for being "over weight" you will always feel like the fat kid, no matter how much weight you lose.
I've struggled with weight my whole life. In my mid 20's I lost over 50 lbs. For a short time I felt great about myself. But a part of me always felt like I wasn't good enough. Flash forward a few years. Finally met some one who I thought I would spend the rest of my life with. Had a few kids and was "happy". Started to slip up, gained a lot of the weight back and started to hate myself again. Now, there was a lot of reasons that the relationship didn't work out, but I blamed myself and my weight the most. We split up, had a very challenging few years. Lost most of the weight I regained. But, I never gained back the little confidence I once had. Still "feel" fat, still look in the mirror every few days and hate what I see. You feel like you are stuck in a loop.
I have had more good days then bad latley. Still, that feeling of inadequacy always finds its way back.
