Text Problem

So I was looking at some tuts and making icons and I dont know what happened but all the sudden when I type text in any size its like TINY! and it wont get bigger. and different fonts will all be the same size. I dont know what I did maybe I clicked off something but didnt notice?

But then if I make a plain white 100x100 icon and try writing in it. It works but I dried dragging the font to the icon that I was making but then in the icon that font appears to be like 407.9 in size but then its the right size.

what happened? im so lost!
