I DONT KNOW!!!!!

I don't know who I am, I have no idea what's ahead.
I don't know your there with me,
but I do know that you'll stay with me.
It hurts so bad to see you cry,
it hurts more when I don't know why.
I know you don't mean to hurt me,
but each time it hurts me more.
I wanna let you know I'm there for you,
but I just don't know how to get through to you that I love you.
