I was diagnosed on a Friday morning and my GP arranged a hospital appt for the afternoon as an out-patient.
The DN was delightful and very helpful. I came away with a shed load of info along with lancets, needles, insulin, a meter and test strips. Somewhat overwhelmed, I did my first injection the next morning (trying to remember the demo the DN gave me) and within days it became easier.
It was a huge shock, but slowly I became accustomed to my new way of life. As an 'oldie' I don't take to changes very easily and this one took some time, but I've got there.
There's a lot to learn, so take one step at a time and you'll soon become an 'old hand' at managing this condition.
