Because probably and very likely you have developed a steong character and self awareness so you wouldn't be negatively affected. For some it could work, but I am sure body shame every obese isn't the solution. 
Trying to constructively show them the self care is the way for much more than body health but also the mind.. maybe.. 

 Fair enough

I just don’t think it’s that bad for your friends and family to point out you are fat and unhealthy when you’re morbidly obese 

Society has gone way to soft 

 Yeap, I do think you absolutely have a point. We should help in every way and push the one close to us in that condition 🤙🏼
