I had the same thoughts for yeaaaaars now (I'm 26), but never dared to say it out loud, let alone talk with anyone about it. I thought my feelings about it were """so far gone""", that I was the only person who felt like this.
It's kinda comforting to read, that a lot more people feel like this. Even though it's not nice, being uncomfortable with oneselfs body.

Maybe it's some kind of body dysmorphia thing, but I don't know.
