My life is pointless, my parents are no help, they shout and complain all the time, everything is my fault and my exams are soon and i have been freaking out for months, my best friend has a boyfriend and i only see her every other Saturday but when i see her she only talk about how perfect he is, or how there not getting along, and they explodes on me when i try to talk to her about me, i text her sometimes and she is usually having a go at me because i'm hanging around with different people, and she isn't even there, so i have no one to talk to.
I need advice, please help me

.
Thanks x
