So, what

So what?
Great question.
So what if my life sucks so bad?
So what if your life is better/worse?
So what is this all for, what are we living for, what does it mean? Does it have to mean anything or are we just a transitory visitor for a brief time?
So what is the meaning, the purpose, the reason, the goal, the beginning, the raison d'etre for all this?

Not to be a downer, cuz this has been one hell of a ride, but, man, is this all there is?
