Happiness?

Do you always find that is hard to have happiness in your life?
So do I.
I will be so sad and depressed every time because of HIM.
I always think the messages are very important communication
and I push myself into a dead end;
but he will just never care.
After I have read the first page of a book which is about happiness;
I suddenly has been awaken, there is a question like this:

"When you wake up every day in the morning,
you'll have two choices;
first choice, you can choose to be happy;
second choice, you can choose to be unhappy;"
and I had chosen UNHAPPY! Why am I so stupid?

The book had mentioned,
Even though there is some unhappiness incidents,
we still have to choose to be happy,
because there is nothing can dominate our happiness;
unless ourselves.
