You are very fortunate to have realized this.
So many never do.
The cause was a complication of extremely brittle diabetes (plus several other things), the walls of the kidneys thickened and unble to adequately filter the blood's wastes.
I interrupted the nephrologist who did the biopsy to tell him - knowing the outcome of what it showed and all he could do was hold my hand while I went down the tubes - it was OKAY....that I know The Great Physician and my Timetable is in His hands; and meant it.
In December that will have been 17 years ago!
A month later the new ACE inhibitors became available and I was started on one to slow the progression.
At the time I worked in a major hospital as a Department Secretary, interacting with the entire hospital and many of the physicians in that capacity.
They were at the ready to comfort me, anticipating my decline, and God had me swinging cheerfully down the corridors for nine more years before the cumulative effect put me on permanent Time Out.
At no time have they been able to better the diabetes control (despite 9 years on an insulin infusion pump), or 'fix' some other things.
In it all, God has been there, and in a dramatic way, before the biopsy, had removed from me the spirit of fear!
His hand is upon me, and my serum creatinine has never reached the point of needing dialysis, still having about 15-20% function!
And just last week when I had my eyes checked, was a most unusual report.
Retinopathy - bleeding in the back of the eyes - and blindness result for many diabetics.
To the amazement of all three of the opthamologists who have treated me, there once was a minimal amount too insignificant to treat with a laser, but NOW there is NONE IN MY EYES!
I give God the credit and glory for my continuing to be able to 'see' and share His creations!
He is there every day, now on two kinds of insulin daily; 2 injections of one - 4 of the other, totalling 6.
In addition, there are 3 injections a week of Procrit, enabling me to make more red blood cells, the kidneys not producing sufficiant epoetin to manufacture enough of them for at least 17 years.
I have tested my own blood glucose levels since September of 1982 - 3 to 8 times daily, and when I worked, experienced between 7 and 12 insulin reactions every week; sometimes 2-3 in a single day. God kept me on my feet even at levels that send most diabetics to ER with seizures.
I have treated myself with a low of 17 - and one day a high of 1,095 measured in my doctor's lab, and went back and finished the day.
The secret of my being nonplussed about all that is that although nothing really works to better my state, and I 'fail' over and over and over daily; God picks me up, dusts me off, and helps me wipe the slate clean and START OVER!!
No one can do that by themselves.
Now you know part of why I praise Him with all that is in me, and could so easily identify with what you posted, whoever.....
