The textbook from which I learned is:
Introduction to Quantum Mechanics by David J Griffiths
I'm sure you can find it for free online or for cheap as a used book.
I caution you that you simply must do the math if you want to understand QM. It's almost all algebra, but some basic trig. and calc. is used from time to time. I have a .pdf of the solutions manual for this book, which will be invaluable to you if you intend to learn.
I also recommend buying a nice, thick, full color physics textbook for yourself. What you want is one that has a section on modern physics. This section is the important one, but everything else will be nice to have on reference as you're thinking through QM.
