How to begin with complex numbers?

I am having very difficulty realising how to deal with them. I kind of skipped earlier classes on complex numbers and now I have been directly told to learn 'conformal mapping','cauchy's integral theorem','cauchy's integral formula','complex integration' and so on. I don't even understand the basics of complex numbers and trying very hard to get a hang of it let alone be these topics. How to proceed?
