May I help?
Don't concentrate on speed. Or, yes, concentrate on speed: concentrate on typing SLOWLY. Why? Because the most important is 1) that your find the letters blindly. Practice not to look at the keyboard. Not even at the screen. and 2) that you type regularly. If you learn to type slowly, blindly and regularly, your speed will automatically increase with time and you'll end up typing much faster than someone who concentrated on typing fast while learning it!
I would practice half an hour a day, not more. Your brain needs time.
If you have some urgent things to say, why don't you use a voice recorder? So you can be creative and express what you have to say. You'll bring it to paper later.
I'd also not begin with words but with single letters. First the letters directly under your fingers, then the ones above those, then the ones under them, and so on. The danger of learning with words is that you'll type frequently used words much faster than the rest, which leads to a lack of regularity, which leads to speed loss in the end.
