I don't feel much for the song... but these words are true
"Life's always filled with ups and downs; a pendulum that never stops oscillating. The good times make us laugh while the bad times make us question ourselves but the truth is that without those little bad times, we will never get to appreciate the good times so so well.
The bad moments shouldn't also deny us our inner peace but rather, we should always take the baby steps at all times in the right direction."
Basically, there are reasons to feel happy about, embrace it... everyday you work to strenghten yourself for the bad times that may came by... you should be all right.
Hopefully if you have good people around you or with you even farer... it helps what say?
