Happy , Unhappy.?

Wondering how can someone be happy and unhappy at the same times?
And that me how i feeling now.
I'm happy after ytd night saying my thing out.
But while still unhappy bout more stuff.
I'm unhappy bout why thing always come so unfair to me.
I'm unhappy bout why will i get this treatment when i'm just concern.
I'm unhappy why cant i jus get what i want to be.
I'm unhappy why cant i be a happy person that i use to be.
I'm unhappy with my LIFE now.!
