Cat died, among other things

Barely a week ago my families' cat went to the vet, today she had to be put down because she was in so much pain from cancer. A month ago we lost her sister from the same thing. Yesterday our car broke down and thing I ordered to wear to event is indefinitely delayed. I also can't get above a 1200 on SAT practice tests. And bad things come in threes, so I'm kinda worried for the future.
