What Is Self-Identity?

This is all I get,
This is what life handed me,
This is all I have to forget,
And everything I have the chance to be.

But this is something that I do not get:
How can life be so uncertain?
And how do I not know the right answers already?
How have I been living this long?
And what is there left to learn?
Does this life end in this physical plain?
Or does it continue in a space that I cannot see?
And is that what I want to believe?
What am I supposed to believe in?
Which religion has the right answers?
What should I find value in?
And what is not worth my time?
Who has all the right answers?
And why won’t they tell them to me?
How come I have to figure this all out on my own?
And why do I feel that no one else’s answers will fit my questions?
How can I be so lost in life?
Will I ever “find myself”?
And what do I have to offer?
What are the truths I can see?
And who do I choose to believe?

Who I am?
