How about picking up a physics textbook? The status quo for Quantum is Griffith's Introduction to Quantum Mechanics. Might I also suggest his E&M book (again, a standard). If you're half as passionate as you portray, I'd also pick up Jackson. That's the standard graduate level E&M book (but a warning on this: to get through Chapter 1 you're going to need to be intimately familiar with PDEs and Green's Function. To get further, I sure hope you like Bessel functions).
Take your passion and use it to drive you to prove. Don't just conjecture and don't try to derive things from first principles. You will get it wrong because you won't actually be working from first principles. Again, don't ignore humanity's greatest invention. It's so much easier to catch up than reinvent the wheel.
Also, you should become familiar with Penrose. I'll leave it to you to figure out why.
Have you done substantial reading?
