I was diagnosed last December and while I feel I am getting to grips with things, I also feel that my life is completely ruled by my diabetes - what I think I should be eating, telling my husband (the chief cook!) what I believe I should or shouldn't be eating, revising this, remembering to do all my (self imposed) glucose tests at the right times , appointments, blood tests, eye checks, feet checks, etc.
I'm on slightly familiar ground though as I had a serious eye problem some years back (not diabetes related though!) and at one point everything revolved around putting in eye drops every hour, and those blooming drops seemed to consist of all my life at the time. I had a little pinger/timer to remind and its hourly pings literally ruled my life...
In part I think maybe that the mechanics of dealing with this sort of major problem help you avoid obsessing too much over the shock of the illness itself?
