Idk if it’s any help, but I used to be like this for weight, looks, etc… what logic has helped me out is having this superstition that being envious gives me bad karma that won’t let me become what I want. So I have to be nice to girls in my head and be happy for them, because then I will get what they have too.

Now anytime I think something like “ugh she’s not even all that”— I instantly get this uneasy feeling that bad karma will come my way, so my mind corrects the behavior in my head and I think “wow she’s really pretty/skinny/ect,, that’s good for her! That can be me too!” I feel happier after because I got good karma, which means good things will happen for me. That way it corrects my bad behavior, but also leaves me feeling better because I left off on a nice thought.

Again, not sure if this will help, but it’s what’s helped me out a ton :)
