Yep...card-carrying extreme introvert here. I trust very few with my private thoughts, which is one of the many reasons why this forum has been so helpful. You can have how much or how little interaction you find useful on any given day...and there's always someone here who knows exactly what you're going through.
So...welcome!
P.S. You're not a mess at all. You're just a work in progress, like all of us!
