Well, first of all, welcome to pianostreet, russianfingers. Also, I am sorry to hear about your teacher, that is hard.
Much of what you will continue to do, will depend on what you
want to do. What are some of your goals with your piano playing ?
More and more these days, I think there is not actually a "right" place to start. There is no universal way for all pianists to start and there is no universal way for all pianists to develop. What matters much more, is how one goes about what one does and wants to do. Some people start with the suzuki method, which I don't know a lot about, but I know that much of the training to begin with is learning my ear and by rote. Some people learn with hand "positions", some people do not. There are many "methods" in the world that will help students to develop in all sorts of ways.
Nobody can learn all there is to know about music and piano within a lifetime even, no matter what
way they started, let alone in 8 years. That's increcibly exciting, don't you think ? And piano/music learning is not a linear process, no matter how organized the education. My point is that you are already developed in some ways, you have already had a beginning that was perfect for then, and that was your "piano kindergarten". You have already been there and you cannot go back, there is no backtracking. The good news is that this means you are ready for a new adventure.
Right now, already, you have a pool of understanding. All one can ever do is add to that, part by part, making the pool deeper, bigger, richer. At the same time, I think it would be impossible to delineate whether we learn something new without it relating to something we already know somewhere within us. In other words, we learn what we are personally ready and prepared to learn.
So the trick is in discerning what it is you already have at your disposal, and then letting that serve you in your other endeavors. For example, a developed ear and map of the piano topography will serve one's reading skills well. Reading skills are simply
one aspect of learning how to play piano music. Just like learning to read a language, reading music enables the musician to have more
options in what they learn.
I think piano and music learning (and learning in general) is like building a rock wall.
When a rock wall is built artistically, and without morter, there are several steps involved. First, the rocks are sorted out from the pile so a clearer idea of what's actually there can be discerned. Then certain rocks may get grouped together, depending on the project they are being used for. Then the wall is started on. Individual rocks are picked out and set into each other and the builder aims at allowing the tightest fit possible between these rocks (and it can look as though they were made to fit together). When the main structure of the wall is built, or parts of the main structure of the wall is built, the builder's helper will follow through putting rock "shims" in the wall.
I think with piano learning, we are always sorting, discerning what is there, building with our rocks and shimming along the way. If you love piano and music, don't let the thoughts and feelings of others convince you out of what you want to do. There is a lot one can do to help with one's reading, and as celticqt pointed out, there will be just the teacher for you when you if that's what you need.
We all need loads of rocks, and we all need a little shimming along the way, and there is nothing wrong with that
