How do I get happy life?

I expect too much?
Maybe.

I'm selfish?
Maybe.

I'm negative thinker?
Maybe.

What I wanna get is just a small happiness. It's not a big one.

How come my life is fulfilled by full of pain, always?

What I should do is, maybe to live for helping someone.

But what I can do now is to live for living.

Nothing else. Nothing is interesting. Such a boring life.

I just need someone to help, and to be helped.

Feeling alone makes me miserable. I'm completely lost my way.

What should I do?

What can I do?
