May I inquire ?

When I was young they told me,
Child you shouldn't lie,
That it's a sin to die-
To kill yourself; see,
God has sent us to the Earth,
To see who worships him,
and to see who sins-
This is the purpose of our birth.
That we should live,
for the glory of God,
and now I think 'tis a fraud.
I do not know who I am,
or whence these insecurities stem

Who am I ? I don't know,
I define myself. Where do I go ?
How do I live ?
When I think, I have nothing to give ?
