I can't sleep

It's amazing how I can be so tired during the day, and then I suddenly come to life again at night. This evening I was watching tv, and I was constantly about to fall asleep. Now I feel like I've just been sleeping for 12 hours.
I even tried to exercise to get tired. And I know exercise is supposed to give you energy, but it makes me tired. Normally. But still nothing.

So now, at almost 1:00 in the morning, I'm lying here wide awake. It's going to be fun fun fun tomorrow in the first lesson. Math. Yay.

Today I haven't done much, other than having been bored stiff at school .. We had 5 fun-filled hours of biologi/physics/chemistry in a row. It's SO hard to concentrate for that long.
I went shopping some time after school, and found 3 really nice new things from H&M's new collection. Normally I don't go for things from H&M, but I actually often find some really nice things there. The only thing I would never buy there is jeans. I don't like the fit of them, and they look quite cheap. But they have some nice dresses once in a while.

Better try to get som sleep now .. Byyye (:
