For years behaviorists have touted the mental health benefits of self disclosure. Revealing things about yourself to others has therapeutic value and also helps forms bonds that improves relationships. This was intended to be on a emotionally intimate level and with people capable of reciprocity.
Humans seem to innately know this, and yearn for it in some ways. Were were not quite prepared for our understood the impulse of self disclosure on social media. This seems to be narcisstic in nature, and the honesty of the disclosure questionable. It is certain not intimate and reciprocity almost impossible. The impulse to disclose fulfilled without the emotional and mental benefits.
In light of what we have all been through this last few years it seems to me how important direct, emotional connection with trusted people are necessary and the key to that is a willingness to disclose.
