Just a thought but if you talk privately with the extroverts out there and let them know what your comfort zone is then you will find that a lot of us will tone it down a bit. Extroverts aren't insensitive by nature we just don't always get it when Piglet clams up because we're just naturally being Tigger, so sometimes we just need a heads up so we can adjust a bit.

I'm an INFJ and sound a lot like you.

I don't know if I'm INFJ, exactly, but I am very introverted. It's very to maintain casual friendships (or start new ones), because I rarely speak. I'll answer questions, but usually can't keep a conversation moving. Social obligations with coworkers are the worst; I always feel like I don't belong. I can get comfortable with people if we spend a lot of one-on-one time together, but relationships can't really progress in a group setting. I'll usually just keep my mouth shut and try to avoid being talked to.

Pick one thing and work up to it. For example be the first to say hi to a passerby. Then when (not if) you achieve that, reward yourself. Baby steps

Sorry, ENTP but without you mentioning that you are an INFJ it would have been lost on me.
