I know what you mean man and yeah it does look stupid, but you were a teenager, not an adult whining like a child over a photo.  Actually weird photos are fun. It's actually "quirky" when I see an unflattering photo of a human. Even the leanest of lean shitlords take unflattering photos; my lifting face looks like I'm farting and orgasming at the same time lol.  I've never heard a nonfat talk about body positivity. Hell even disabled people I know hate that shit.
