I don’t know why should I live.

Please read and comment. I am 14 years old, and a boy. I don’t think I can take this much longer. Earlier I used to be a school topper(Currently I am in Class X). In class 7th, my rank dropped. From that point on my life has become hell. My mom is of a very high temper. She now keeps abusing me all the time and beating me. She keeps telling all my friends and relatives that I am a failure. She even broke my Lumia 820, which I ordered by my own money(Google Adsense). I don’t think I can take this anymore. I have had a crush on a girl, since class 6th, but never got the courage to say it to her. I love her so much, she means the world to me. My friends are my only supporters and due to my mom, I am most of the time cutoff from them. This year my mom changed my coaching. Earlier, I was studying in a coaching for almost 5 years and loved it. My sir knew everything about me. Mom criticized him saying that he was the reason of my failure and abused him and I couldn’t bear it. I just don’t think I can take this anymore. Please help.
