I agree a lot with this. I'm shy introvert and low confidence, and started going bald before 18. But somehow I never felt ashamed of going bald. I kept on being shy introvert and low confidence, but not having a lot of hair was more or less the same as having two hands.

The point being: having or not having hair, muscles, big tits, big penis, beautiful hair, a high IQ, wide shoulders, a quick sense of humor, a lovely accent, a big car, a sexy startup, a cool job description, or whatever, are only proxies for "perceived self[1]-value", that one can use to either gain or lose confidence in him/herself. This is happening right now in your head, and it is a positive-gain feedback loop that's harming you. You need to identify it as such and find ways to cut that loop. Being unable to relate to the other sex is just a consequence of that destructive loop, not the actual source of it.

[1] Mind you that the rest of the people don't evaluate such factors to the same values as you, and don't place the same weighting on them.
