I'm glad the "worry" one helped.
Low self esteem has many consequences. Two of them is not being defensive enough nor, when required, aggressive enough.
E.g. if you were in a cafe and someone overheard you talking about, say, how you felt you didn't fit in at the local Lions club and a stranger from behind you commented "I fitted in, it must be your personality". My immediate and swift reaction would be "excuse me, this is a private conversation "
Low self esteem muddies the waters of right and wrong because we haven't got the confidence to enforce our beliefs even when we know we're right. That results in some people, nasty, narcissists, manipulators, to walk all over us.
Eventually we often withdraw and become less trusting.
Raising low self-esteem is imo a case of shrinking your social spread and filtering strangers well before trusting.

All this can result in a secluded existence that is better than the fear of saying something you are regretful of.
