Happiness comes in different forms, you may find your happiness within alcohol, drugs, sex, addiction, another person etc.
You should never rely on something or someone to make you happy. Happiness is found within yourself. Although you may not know what makes you happy at the moment, that's what life is all about, finding or doing something that makes you happy.
Find your way, do something incredible, take chances you would never do, this is how you find your happiness. Money doesn't make you happy, you make yourself happy. No amount of money in this world will make you happy, it's not about how much money you make, the clothes you wear, or all the nice things you have.
All of these things will eventually go away, when it comes down to it all you've got is yourself, and you're the one who's got to make you happy. Take a chance, do something you would never do, go out of your way to make someone smile! If you're just moping and walking through your life daily, stop and think, is this what is making me happy? If the answer is no, change it! You have control of your life.
Find what makes you happy and make something of it. If you aren't happy in life, then you're sure as hell aren't living.
