I've always wanted to ask people this question!
I'm in high school now - well, actually, in the NL's junior high and high school are combined.
Anyways, the first 2, 3 years I hated it (that's junior high and the first year of high school). I had a couple of very good, close friends, but I was really, réally shy, had a véry low self esteem and I'd been depressed for a year.
This year though, is totally different. It's weird, I don't think I've changed a lot or something, but somehow it's just better. I have a lot of friends, acquiantances, I can talk to everyone without being extraordinary shy, and I have lots of fun!
