Why owh Why

Why owh why am I keep feeling depress these days,
Arghhh feels like everything I do keeps going wrong,
I made wrong decisions,
I think I spoiled some of my friendships,
I'm bored to death right now,
And certainly doing nothing at home,
I'm ruining my life,
But the question that I keep asking myself..What did I do wrong?
Is this what people call karma?
Or it is natural to feel this way because sometimes life has it up's and down's?
Arghhh it's all blur for me,
My chest feels like it had been dug a big hole in it..
Must try to break free from this boredom and depression..
