I got rid of my Facebook because I just never felt comfortable posting there and that's when I did have some idea on what to post, so I see where you're coming from.

Sometimes I think we need to stop beating ourselves up for being introverts. We're no worse a person for it - it's just who we are. And who's to say all extroverts are really that happy anyway 🤷‍♀️ It does become a problem though I know when you really want to pursue a particular thing and shyness stops you.
