Time Is Running Out

I realise the rhyming and syllables make no sense. Couldn't make it work otherwise.. ^^

Time is running out
I hope my words won't fail me
I'll say it, I must
Before I've missed my chance

My boundaries are failing
My arms flailing
I can't keep it in
But I fear I won't

So many 'what if?'s
So much confusion
So much inside me
That I must learn to show

If I won't tell
Things will stay the same
In this frozen, agonising state
So close, yet so far

If I do, it can go either way
Either my world will be blissful
Or stop in a moment of pain
That three words can shatter
