Communication anxiety prevails. Awkwardness is a fate worse than death. Being silent, isolated, and avoidant is the only path for anyone who is not a naturally gifted communicator. And that last part is the worst...because almost everyone except for you seems to have an easy time with conversation and communication. If you're struggling, well, you're one of the weird outliers.
There is good news, and there is bad news.
The good news is, you are not the only one struggling. Many people-- I believe the majority of people-- struggle with conversation. The bad news is: it's because conversation is actually pretty hard. The struggle is real!
