I never knew that I wasn’t fit for this world. I’m not sure about the only child but I had friends who were only the only child and turned out to be fine. It’s all about genes. Two of them are slayers and one is a normie. Being a good looking only child is a good thing thing.If you have overprotective parents and was a good looking only child , you would’ve still made it into the world due to the constant positive reinforcements by society. Being invited to parties, girls sucking dick in hs toilet, getting a lot of likes on social media would’ve made you realise your value and get out of your shell.Genes can overcome bad circumstances imo.
