What to do when everyone is trying to bring me down? -

I constantly feel like sh*t nowadays. I m studying 4 subjects at A level, and I m heading for an A in one and a B in the other. The other two I m failing. Overall, I dont think I m doing too bad considering I suffer from depression and most of the time I have no motivation at all. My attendance is above 90% all the time. My parents constantly tell me I will end up working at a cash till the rest of my life, and that I should retake the year and do different subjects, and that I will never have a job I enjoy that earns money. And then my teachers tell my parents that my hearts not in any of my subjects and that I need to put more effort in to get the work finished. I cant put any more effort in without pushing myself into exhaustion. Basically I m sick of this. My parents make me feel like a failure and sometimes I just really think none of this is truly worth it. Help?|::::|There s your motivation first win all your courses and next school year aim for a high average and RUB IT in every body s face. Prove them wrong show them that you are better than what they think and they are soooooo wrong for underestimating you. Think about the motivation you need is right there you just need to focus on it.
