I don't want you to take this the wrong way. I've received countless ugly comments on my writing, ugly reviews, put-downs, been standing where others couldn't see me and heard heinous and insulting things.
I think you are not even vaguely close to writing anything honest. I stopped reading because my sense was that either you are still seeking to purvey a certain desired image to others little different from your article's thesis, or - look, I hope it's not true, I hope I am wrong - this really is you.
And if this is you, this is your life, it is a sad thing. There's so much more to life than this. So much more than eating, school fears, the way kids treat each other, so much more than a firmly-held belief that the disease of anorexia (which runs in my family as well) is what our lives revolve around.
LIfe is SO much more. Being a whole person, having character, not thinking that everything we think or do is the end all and be all? Yeah, that is life. I'm not sure if you're still in your 30s, but if sex is your concern, 40s and 50s is better. In general. Biologically - and if one is secure and happy, very good. Namaste, good luck.
