Who am I ?

Who am I ? Day in Day out l try to decide, Somehow got lost along the track, Not knowing that I'm heading towards a wreck. They say everyone has a purpose, But I just cannot find mine, Forgive me but I'll be just fine, I've become a detective of my own life, Trying to solve a mystery of who am l, No matter how hard I try no luck, Trust me it really does suck. Tik tok, Time is running out, My head is full of doubt, About my wonderful past, Which has turned into a miserable present. Many questions in my mind, But only one answer required to find, Will never rest until I find peace, My peace lies within the question, Who am I??
