Jordan, maybe I can help. I've been teaching myself for 3 years, and I've been through this feeling. But I also use a lot of different methods to study now, and get by a lot of it.. maybe it would help to practice more? How much time per day do you have that you can dedicate to learning Russian? And are you wanting to be a good book-reader, or good speaker, or both, and in what order of priority?
Are you going to use the language socially, militarily, in business, or full-time (residing in russian-speaking lands)? This would make a big difference as to your best approach. In Business, I'd imagine you want to know it well enough not to miss things that are said, which could be small but vitally important.. meanwhile if you're going to be a teacher in Russia, you may only need what is necessary to get around, and so on.. What's yo' plan?? =)
PS - Jordan, are you native English? Winnie the Pooh is written by an English author, if I'm not (extremely) mistaken (isn't that right Christopher Robin?) .. so if you're not UK native, it might be harder because of some odd forms.. just putting that out there.
