Insecurities

I'm back to school.  Feeling old as I hear about the other students in my class, wondering if I'm older than any of my teachers, struggling to figure out the technology side of classes, and getting back into good study habits.

For the most part school is going well.  Classes make sense.  I managed to pass both my classes last term and I'm feel confident in the classes I'm taking this term.

Except for one thing.  It's a silly thing.  It's not important to the class.  But it bugs me.  Yesterday I ended up with a headache because of it.  My teacher didn't reply to my introduction on the chat board.

He responded to everyone else but not me.  So I immediately decided he hates me.  What other explanation could there be.  After all teachers never overlook things, they never make mistakes, they aren't even human, right?

Okay, I know I'm over reacting.  But I still wish he would respond with "welcome to the class" like he did everyone else.
