Hope you all have a wonderful song

I am who i am
Do not come near and do not know
I am in the heart
I have kept
You go and see

I never thought I could
You get
I am in your life
Get involved
Breath by the breath
How much do you mix
Do not understand

I do not know any light
If spread
My world
If filled up
Believe in faith
How much do you mix
Do not understand
