*Sigh* I can certainly relate that this one. At my old middle school, students were to remain in the halls of the bottom floor until the morning bell rang. Well, it was a little into my sixth grade year, and I did not know where the bathrooms were on that floor, and I couldn't seem to find anyone who did. I ended up throwing up the banana I had had for breakfast... in front of a couple hundred older kids. Humiliating, to say the least...
I, too, was completely terrified to return to school. And yes, I did get some weird looks, some snickers, and a few rude comments. But I learned to just ignore them, and, eventually, everyone found something better to converse about. Just tell her that it will be hard at first, but this too, will pass. From personal experience, I sign out...
Good Luck to the both of You!
