Why now?

So....you know how my relationship with my dad ended? Well, a few days ago, I found out that my grandma, who doesn't have much time left, has gone mute. She doesn't say anything anymore. Anything. And today, 5 minutes ago actually, I found out that my dog has a year to 6 months to live. Why is all this happening now? All together. I know that time has to move, and people have to die, but all at the same time? That's more than a teenage girl can bear, especially with everything else going on. But the world, much like my problems, has to go on. And I am being dragged behind because I forgot a step.
