My depression

I wonder what's the meaning of my life. My friend said there is no meaning for everyone life in itself, but it's just made by each person who is making in oneself. when I heard that, I thought 'so.. to make happy life, what can I do for me?'. Honestly, I don't know anything now.
Recently I don't feel happy or satisfied. many people say this is depression. I want to overcome this time. so I exercise everyday, but it is not getting better.
