The thing is this modern society which often treats dependence as weakness and independence as the professional level. Yet every meaningful part of human life is built on connection, even the same system, which I believe is the reason behind all this, works on the model of community level cooperation. We learn from others, heal through others and find purpose through relationships. The paradox is that while we all carry burdens, many of us have become hesitant to either ask for help or offer it. Like even offering it is becoming a negative thing nowadays. And in trying so hard not to need anyone, we sometimes create the very loneliness we fear.
Moreover, I think vulnerability is deeper than simply admitting our struggles. It requires the courage to trust that human beings are meant to support one another. Many people are not unwilling to help; they are uncertain, distracted or afraid of crossing boundaries. The whole concept of rigid individualism is causing quite harmful effects. A healthy community is not one where nobody has needs, but one where needs can be expressed without shame and support can be offered without judgment.
Btw, this capital system promotes taking as much as you can, while giving bare minimum in return. So psychologically, we are being trained this way :)
