You obviously know how to 'work' reddit because this is your published post. Being an introvert isn't a disability or a character flaw. Introverts are shy, focus on inner thoughts and aren't comfortable with public speaking. Reddit is anonymous with no public speaking. That should take care of the "I'm pretty introverted" part.
