You are a chance?

Sometimes I think I find you by chance
You came to my world when I was desperate
I worked hard day to night and I thought,
this is the only way to live a life
You came and made me depressed
cause I thought you would change my life
from the bad to the worse
How could I work as hard as I did before?
How could I have my time as I had for my own?
How could I have baby when I not grew old in my heart?
But any way; you came
And first I thought I find you by a chance
And this would be a chance to change my life

Now I think something else:
How come if you find me by chance,
to change your life;
and mine too.
