No it isn't!

Course I don't know why you're saying that and don't really know why but...

I can guarantee you your life is not a waste.

Care to elaborate on what has you so blue?

My Mom's not happy with me right now.
It's okay, I'll play some pong until I feel better.

So parental troubles. And sounds rather serious. I can't really say to much without knowing details, and from the sound of things you don't want to talk about details so I won't press for them.

But rather you had a major argument or made some kind of serious mistake that does not make your life a waste, useless, or meaningless.

so true, there's always a light at the end no mater how dark the tunnel is

please cheer up
it iwll be better soon

What? You're making this declaration now? And so early on in things? When you have so many years left to fight? Why call it quits now? The starting gun has only just gone off.
