My mother has yelled at me everyday for the past 3 weeks because my grade in Government has gone down to a C twice. Not just Government, but ever since 7th grade, my mother just constantly yells at me, it's made me depressed, I always think: I'm not good enough, or I'm worthless. It sounds sappy, but I say it everyday. Usually I just listen to Avenged Sevenfold(for you guys that don't know, its a metal band) and try to blow it off. But it constantly bothers me. Help?
