I've always loved quantum physics and recently came across lots of free time i was wondering if anyone had any websites, books, etc. that could help me learn more in depth about it like the math, equations, and more. I already now almost all the basic theories, particles, forces, and basic science behind them.

Go to Khan Academy for your maths and basics. Then go to edx.org and sign up for some free courses at about 1st year undergrad level. The shocking difference between reading pop-science and actually learning real science is brutal - and frankly, once you get a taste for the hard stuff, pop will never satisfy again.
