Hey Christina!
Nice to meet you.
I'm sorta-new too. I joined months ago, but haven't been on the forum in a month... and I haven't really been on the 20-somethings before.
Anyway, I'm in university too, and I'm just trying to get healthy.
I totally find my weight gain mysterious too. I know I must have been overeating, lots of sugar and junk, but I don't remember what I was doing or exactly when I gained it all.
Welcome to you anyway, and enjoy the forums, they are excellent for advice and such. Many different points of view, and lots of successful losers to help you along
