The me before..

i do remember i had a lot of fun.. with myself, family and friends, before this, nothing in this world can make me unhappy, except that if ppl that i love are hurt.. but now, everything seems to be different, is it me? or something else? i really want to become like last time, where nothing can trouble me.. i can see difference in my smiles from the pictures. it is so scary.. before, everytime, when its picture time, i would smile as wide as i can.. but now, my smiles are now so fake, i would love to take pictures, but now, i hate being in the camera.. everything just changed completely after i came to college... why?!
