No, I've been lazy and I'm REALLY good at speech.
I'm finally done studying, I mastered A I U E O.
I'm not sure there is any value in responding to this thread as I am seriously doubting its legitimacy. Never-the-less, for the sake of those who might use this thread as reference or on the slim chance that this thread is legit, I'll answer.
Ignoring the fact that there are many statements you made that seem to go against each other, if you want an answer to your question; like NiceGaijin and Ashikaga said, not knowing Hiragana after three is pretty bad. I'll go far as to say it is freaking awful to such a degree that is it is the very foundation that behind why posters question the honesty of this thread.
So yes, it's bad. Very bad.
As for your speaking being really good. Please type in roman characters to prove it. We need to see in order to help you in that area in connection with writing as well. Once again, assuming you are being honest, then writing and reading is where you need to catch up on. If you do not have an understanding of a reading and writing system, you are missing a very large foundation of a language that will also help you expand your speaking and listening. Everything is connected, and the more you know from different aspects the better the chance to remember and the stronger it is stuck in your brain. That should answer your question on how to remember things.
As for a general time line, when I first learned Hiragana, I had the basics down and the characters memorized in a little under two weeks. It was the first thing I learned. As for Katakana, I'd say a week, but it was ongoing since I would forget a few sometimes due to not using it all that much at the start. I see no reason why you shouldn't have everything memorized much faster considering you claim your speaking is really good.
On the comment of wanting to live in Japan... If you can't even focus to learn Hiragana after over three years, then you had better seriously rethink your own personal motivation and personal abilities in regards to moving and living in a foreign country. It isn't a minor thing, and living abroad takes about 70 million times the dedication and effort that learning to write hiragana does.
This will sound harsh, (I guess not really since I'm even taking this thread seriously) but listen to it well. Get your act together (as you claim to be doing) learn the basics of the language, learn to focus and complete set goals, and take a trip to Japan before you EVER think of picking up your entire life and jumping over into something you are completely unaware of yet.
Then again, you clearly knew the answer to your question before anyone replied anyway from the way you posted it. I can only assume you were looking for the push... or you were a troll. The first we don't mind giving, the latter you can congratulate yourself on wasting honest people's effort and exploiting the kindness of our help.
Good luck
