I don't think our self-worth is based on anything external to ourselves. Self-worth is basically about whether we feel we are generally "good people." If we happen to need others' approval or validation, that's okay, but that might be more accurately called "other-worth."
My unpopular opinion I wish to share is that when medical professionals ask someone to rate something subjective, like pain or anxiety, using an objective scale of 1-10 is ridiculous. Some things can be a 1 for one person if they happen to have a lot of experience with it, and for another a 10, if they haven't experienced it. I have even had people ask me to rate nausea on such a scale.
