I'm trying to repent over lust, but it's driving me insane?

I understand nobody is perfect, but doesn't God want us to follow him? I am working on the 10 commandments and 7 deadly sins right now and trying to not do them more and more everyday but the most difficult one is lust. I get very depressed every time I think about not lusting, because it feels like instead of having pleasure I am suffering. Any words of wisdom?
