where is the honestly smile of mine goes?

I'm a person who love to smile... =)
while talking or even when listening to others....
but...i realized is't a real and honestly smile of me in this few weeks....
hidding from some sadness and problems infront of others
and act nothing happened....
and just a little smile on my lips....
smiles, makes me feels there is life....
no matter what happened, need to faced it with a positively ways....
this is what I wish I could do...for the comings day...
wish everything good will come to me...even there is UP&DOWN in life...
the one who loves you, is yourself...
so...I should learn how to LOVE myself more...
