Why am I afraid of talking to people while at the same time I wish to talk to someone?

I am afraid to talk to people maybe because of the fear of being judged, or maybe because the last time when I tried to make a conversation with my peers they belittled my input. I am afraid to talk to people because they not just belittled me but also made me doubt and ponder over my poor existence. But thanks to the irresistible force of conformity, I sometimes feel incomplete and discontent. I just wish to talk to someone to hear me out, to hear my cry. This is humane and I shouldn't care if somebody judges me on being this way because I know the dilemma I am in will resolve one day. And that day isn't very far.
