It's 50:50 with me.
My parents didn't teach me self confidence, or treated me so i could build it on my own.
There usual words were "dont be a baby", "dont let them get to you", it's easy to say if you are not ugly. My parents were not ugly.
But, i partically blame myself for my bad mental state, i am weak to a fold, but what do you expect from someone who is and was mistreated youst because his face isn't pretty.
Thze most blame of course, i blame on soyciety, it's really horrible to experince discrimination without anyone ackknowing it or even believe you.
I am again sorry for my bad english grammar, not a native speaker/writer.
