Amen. Im totally there with you man. I used to be into bodybuilding and it turned me into a maniac and totally gave me disordered thinking with food. Since I decided to go primal, Ive finally felt normal.. then I had the thought.. " you know.. you will get better results if you calculate your calories" and so I started doing that again.. then I started obsessing about macros again.. and like you I crashed hard. So Ive picked myself up.. dusted myself off and Im going at it again.. only this time.. Im not going to worry about calories and macros.. Im just going to eat like I have some sense. Life is far to short to be obsessed with food. It is a very tough habit to kick though. Anyway.. no real point.. just wanted to say.. you are not alone!
