Why do you live ?

Hi I am Joker.
I don't know the reason I live.
I am maybe living for my parents.
If I die early, I guess my parents will be very sad. Don't you think?

I am a college student.
In my last exam, I had studied hard and I got a good score.
I think I have many good friends.
...
So what?
I don't know why I live.
I'm not sad and won't spoil my life.
Just .. I don't have the reason I live.

I know what you're getting at and I've felt similar to this. I also suffer from depression which makes it worse. I don't know if you have depression or not so I won't say anything about that. You just need to find something that makes YOU feel happy and like life is worth living. You just need to find something to look forward to. Are there any goals you have or is there anything you want to try before you pass away? Is there any place you want to visit before you die? You have to think about those little things, babe! ^^ I hope you feel better and are happy.~ Good luck. ♥
