How do I make that?

You are my two ways
Can't go, can't stay
None of those is clear
In every one I see fear
It's mine. "Easy" you say
But the price to pay
Seems so big and yes
I know it will rest
In peace with me soon
Nothing is forever
Not even the Moon

My coin of two sides
It's you and you smile
Knowing that any part
Will be another start
For us but one is dark
Like in an adventure park
Joy walks next to death
I'd just like to rest
Nothing is the best
Even staying here
When I stay and fear
Between two roads start
How do I make that?
