Smile?

*a song from Glee which i relate to now*
Smile, though your heart is aching
Smile, even though it's breaking
When there are clouds in the sky
You'll get by...

If you smile
With your fear and sorrow
Smile and maybe tomorrow
You'll find that life is still worthwhile
If you just...

Light up your face with gladness
Hide every trace of sadness
Although a tear may be ever so near
That's the time you must keep on trying
Smile, what's the use of crying
You'll find that life is still worthwhile
If you just...

Smile, though your heart is aching
Smile, even though it's breaking
When there are clouds in the sky
You'll get by...

If you smile
Through your fear and sorrow
Smile and maybe tomorrow
You'll find that life is still worthwhile
If you just smile...

That's the time you must keep on trying
Smile, what's the use of crying
You'll find that life is still worthwhile
If you just smile

This song keeps playing in my ear and in my head, over and over again, much like a broken record..
And i wonder, is it ever this simple?
smile, cuz it’s better than crying..
Smile, things will get better eventually..
smile...

but what if all the negativity surrounds you so badly, you cant even muster the energy to smile?
What if ur heart truly aches, and smiling doesn’t help soothe da pain?
What if ur down and u dun wan others around you to worry.. yes, smiling conceals our pain and puts others around you at ease.. but deep inside you, you’ll wonder, how will you get through this?

*need to find that glimmer of light to return to my usual cheerful self*
