An English poem

I remember when I was a child
And when I wanted to sing songs for a while
I locked myself in an island
And dreamed of echo my voice

I remember when I was a teen
And everything looked so lonely and sick
To play my acustic guitar as my only company
For a moment my dreams were buried in a distant hill

I lose myself
There's no one else
Although my own
To take me there
To leave me from all of that
Once I released my mind

Now I'm not satisfied (I'll never be)
Why am I not just happy to be alive?
Why's so hard to think the better word to follow the rhyme
How many available time do I have? (never enough)
How many unecessary questions
