Another point worth mentioning: Math in general is heavily interconnected. The more math you do, the better you become at it. A large amount of math is knowledge. That mess of symbols is something you will have to understand. As soon as you understand what it means, everything is just trivial.

My advice would be to start with some books you can understand and then build up there towards your goal. It may take a couple of years, but the time used are going to be paid back in masses when you hit other math problems: They suddenly got easier too!
