Advantage and disadvantage of vulnerability

Vulnerability is the quality or state of being exposed to the possibility of being attacked or harmed, either physically or emotionally.
ADVANTAGE OF VULNERABILITY
One of the most crucial benefits of vulnerability is that it builds trust and intimacy in relationships.
Less stress/tension By being vulnerable, on the other hand, you eliminate this unnecessary tension and experience a higher level of freedom.
DISADVANTAGE OF VULNERABILITY
vulnerability is appealing, it can be risky. We may be hurt, laughed at, betrayed, criticized, shamed, bullied, or made to feel guilty about our behavior.
We may fear that we will be viewed negatively—as naïve, immature, unintelligent, neurotic, or perverted in some way-- after revealing too much. The worry underlying such fears is that if others really knew us, they would think less of us.
Other risks of vulnerability are losing control of the situation, being disappointed at another person’s reaction, and rejection. Telling someone that we are depressed, for example, may lead to too many phone calls and other intrusive queries that we may grow to resent. Or we may relate a painful life story, only to have the other person react indifferently, angrily, or critically, thus adding insult to injury. Then, too, we may fear that after sharing something important, the other person will turn their back on us and walk away.
