Raipizo, take it from someone who learns a lot from books. You can get the words and the basic "left hand goes here" from books. With practice you can make the transition from X to Y smoother. So books do have a place. However, you can't really get good feedback from a book and that's where you need an instructor. If the sifu is good, and folks here seem to think so, then try them out and maybe be willing to pay a little extra to get some one on one before or after class. A good instructor will be able to give you things to practice at whatever level you're at.
Be diligient in your training and creative in finding a way around obstacles. Or be honest and admit that this isn't the right thing for you right now. I've lived in or near some really bad places and if you really want it you can find a way to stay safe and still get what you need.
