Good Morning Megan, I just saw this now and wanted to post a special good wish to you although I do have that day on my calendar to send you a special pm.
You have received such an honor to be accepted into the this school and although the first couple days will seem different because you think of yourself as shy BUT look at all you will have in common with these new kids that you did not at your previous schools. You are leaving your comfort zone and that can be scary but most will be overwhelmed too so why don't you reach out to them and introduce yourself and in a few days your lovely personality will shine forth and you will have many friends thanking you for helping them though this first or second day. Just a thought and how ever you handle it, you always know best. Love Ya. Joan
