I want you to make me happy

I read this today... and make me think that I did too much for other people in the past.

I always think if I can do something for other people, they can feel how much care I concern about them. If they can be happy, I will be happy. But unfortunately, there's no such rule in the world. No matter how much you do, you cannot expect what you can get in return. On the other hand, what can make me happy? I also want to know.

"I want you to make me happy!" Can I just request someone to do it for me? No... "Why do I need to make you happy?" "Who can make me happy then?" It's an endless questions and answers.

I am totally confused and I still need something to heal me which I don't think I can find it...
