Hi there,
I, too, have had considerable malevolent feelings since being put on insulin for my LADA but am gradually overcoming these feelings. DVLA is sorted out, I have a 3 year licence so am still mobile. There are many rules to follow but........ No matter, they are in place to support safer driving by me, shame it doesn't extend to other road users. The insurance is fixed, no extra costs, just happy that DVLA are aware.
As each "problem" is put to bed the load is getting lighter and so are my moods.
Hang on in there.
