What you've done so far is absolutely magnificent. Congratulations on your determination to control what happens and not allow it to control you. As we know, it's anything but easy to redirect our efforts and change our habits in the way that you've done. Great job!
When it comes to dealing with what still lies ahead, the best strategy I know of is the one jrtpup stated, above: take one small step at a time, concentrate on just that one piece, and forget the rest until that one is handled.

When faced with a problem you do not understand, find a part that you do understand and do that. Then step back and look at it again.
With diabetes, as with life, the #1 most important requirement for success is the right attitude and the determination to make it happen. You have that in abundance. I know you'll succeed.
Please stay in touch and let us know how you're doing!
