If you're only 14, you probably don't know enough math to really be able to follow the presentation in the standard textbooks, but I'm not going to discourage you from trying. I say go for it. Even if it fails, you will get a better understanding of what math you need to study before you give it another try. So I will take your request seriously and recommend a few books of the type you're asking for, but I have to warn you that you will probably find all of these
very difficult to follow.
Griffiths looks good to me, but I've only read a few pages in it. I've seen comments saying that Shankar is better. Zettili is getting great reviews at Amazon. The book by Park is only getting a 3 at Amazon. I'd be concerned about that. I really like the book by Isham, not as an introductory text, but as a supplement to one of the others, to help you understand things better.
It's impossible to learn QM well without at least knowing some linear algebra. My favorite book on linear algebra is the one by Axler. He's doing things
right.
If you decide that you want a softer start, you might want to consider an "introduction to modern physics" book. People usually recommend that type of books to people who don't have the mathematical maturity that the authors of the books mentioned above expect their readers to have. I haven't read any such book myself, so I don't know if I would have liked it or not.
A few comments about the math: It's essential that you study complex numbers. You also need to know a little calculus, but only a little. When you understand what a derivative is, and what an integral is, your lack of knowledge about the rest of calculus isn't going to be a major obstacle. Linear algebra is much more important. You need to at least understand vector spaces, linear independence and bases, linear operators, matrices, the relationship between linear operators and matrices, eigenvalues and eigenvectors, and inner products. This is college level stuff. It's easy compared to a calculus class in college, but when you still have several years of high school left, you may still find it very difficult.
