So much of what others have written is true for me. I get to school [excessively] early to work out and then prep alone in my classroom, occasionally eat lunch alone, and sometimes hit the bathroom just to have a few moments to myself (especially when I'm feeling "off"). Teaching is acting for me. I play a role that I don't exhibit anywhere else in my life. And that's ok because it helps me BE a teacher. One area of my school and personal life that has suffered due to my introversion is my [lack of a] social life. I have no energy to do anything other than sit at my computer after school. I don't go to extracurricular events (which I know is helpful for building relationships) and I don't have any friends. It's something to work on. But first things first: get through the school day! I hope you find some strategies that work for you.
