why AM I so confused???

What is Life??? Its purpose??? What are we doing on earth??? Why are we here on earth???

I have been thinking ALL my life....What is the purpose of my existence on earth??? What am I????Who am I?? Why am I????
If I take Reference from Quran...or concentrate on the teachings of Islam..I might understand the true meaning and Purpose of life......But do u really think I wouldn't have done that already?

A human mind is never satisfied!! and is ALWAYS in search of answers...and even AFTER it gets all the answers!! It doesn not stop there!!! And the quest continues!! The chase continues!!
Human beings (ashraf-ul- makhlookat)have always been in search ...In search of a lot of things...In search of happiness, in search of mysteries and in search of God!!!
do u know where God is????? We KNOW he exists!! exists everywhere!! BUT exactly where????
human mind has lots of gray matter..folds...gyri...sulci.... BUT still its TOO LIMITED!!limited to only the kind of thinking God allows us to have.
YES..it is Allah's will that we cannot think beyond our knowledge,beyond our imagination. TIME , SPACE....Are only relative entities...What is TIME?? Do you know?? Do I know?? Just a relative term or period, created by Allah to explain and relate certain things to us. There are no time limits where Allah Almighty lives...Where heaven and hell are sited.
BUT where does Allah Almighty live?? Why cant we see him?? What does he do all day?? Are there days over there too?? over where?? What's this all about??
Again the same question...why are we here on earth?? Where is earth?? Near Allah?? Near heaven??
What does our existence mean? why were we created?? If the entire universe was created only and only for Prophet Mohammad (P.B.U.H) then why were WE created??
WHY??
If there is destiny..If the good and the bad souls were pre determined..then why were they sent on earth?? When nothing I do can change my destiny..then why do I have to do anything in the first place??
The" what", "why","when", drives me crazy...and all my life these questions have popped up in my mind one way or another. Why do I keep struggling to seek answers. Why can't I just stop thinking? I CAN'T coz Allah Almighty has made me like that, has given me a brain to USE n not waste...BUT ....WHY???
why can't I be like the millions of girls that I know...with no worries...the girls for whom "why", "what", "when" does not mean anything and it does not interfere with their lives...all they worry about is the next day...what they would wear...what they would say... they do not want to think where they will be ten years from now...their only worry is their boy friends...their most important relationship...no other relationship matters to them..and their world revolves around them...I wish I could think like them..I really really do!!
I still don't know what my existence means..and what I am doing?? why was I created?? to fill the gaps?? spaces??
YES I accept I have reached a certain milestone in my life...and for the past many years THIS is all I wanted...BUT now...I am not even sure if that's what I actually wanted...I am confused twice over!!.. What do I want now?? Will I die unnoticed like millions of people around me?? Was I sent on earth just to be a part of a BORING play?? Was there no special REASON for my creation??
Why after achieving all this, that I once thought would be enough for me,I still think I am standing no where?? why do I feel there is A LOT I still have to do..NEED to do??
Maybe coz the real battle..the real play has just not begun yet!!
God....I really am confused!!
