You don’t feel bad about being body shamed because it makes you conscious about your body.
You feel terrible because you start thinking that you are not good enough to be accepted.
You feel let down because it tells you, “If you want to be taken seriously, if you want to be appreciated for your work, look a certain way and wear something communally appealing! Conform to certain set social standards of looks and attractiveness for your respective gender group first, and then we’ll give a thought to your existence!”
Your credibility, your integrity, your knowledge – none of that, absolutely nothing else matters, but your looks.
And that feeling can be devastating.
