How can I deal with this? Why does bad stuff ALWAYS happen to me?

Seriously, I feel like I have a curse on me or something. Things almost NEVER go my way, and being a klutz doesn't help much either. Right now, I have a HUGE problem. This week, I accidentally ruined the earbud jack in my MP3 player (don't know how, but now I can't hear anything when I put earbuds in) so I told my mom about it, and she was totally understanding because the MP3 player was kinda old and was pretty cheap. But today, I got pushed from behind at school and managed to drop my cell phone down the stairs. It fell down four steps and the screen shattered. It's a pretty pricey phone, my grandparents bought it for me as a gift last year. I'm totally afraid to tell my mother, especially because of the MP3 player thing happening JUST a few days before. My mom currently wants to replace her old phone and buy a new one. She says she will give me the brand-new one and she will use my phone. I really appreciate this, but how can I tell her that there is no phone for her to take? She is really, really strict about taking care of one's belongings. I was considering telling my grandparents first about what happened, but I'm afraid that everyone will get mad at me for dropping the phone, even though someone else pushed me. What can I do?
