Who am I? What is love? Why are we all here?

When ever I look in the mirror, I can't help but to ask; "Who am I?" "Why am I here?" Do we all have a purpose in life, or is that something someone made up to explain our existence.

What is that love thing? Is it something we our minds create. People say "You can't help who fall in love with" but what if you can, what if you do in fact pick Or is the soul mate thing real, are we predestined to met someone who completes us? But what if you don't met that other person? Does that mean you never get completed? If that's true than I'm screwed, I have this friend who told me that I'm never going to fall in love because I have a wall build up around me. So does that mean that I will never get the feeling of being whole? Can't I just complete myself. Shouldn't you be able to compete yourself and finding love just be a chary on top?

Is there a God? I know I lost all my faith in him. But if there is a God. Why did he put us all here? Are we just some experiment? Does he in fact love us like the church says? If so than why does he let us lead such fucked up lives? Where is he? And why won't he help?

Why am I here? What is my purpose? To be frank I really don't have much to offer the world. What is my purpose? How do I know what it is? And how do I know if I'm fulfilling it? Or do I not even have a purpose at all?
