Hello and welcome to the forum.
I'm sorry you seem to find that this site only fuels your concerns but I have to be truthful and say that I think your remark about a lack of support is rather unfair, given the fact that you have never posted here before asking for support for yourself.
The whole point of a support forum is to do just that, support and possibly advise those with concerns. Most of the forum members (in fact nearly all I believe?) are diabetics and we do our best to help each other out.
Regarding the issues of driving licence etc, if people are worried, surely they are entitled to ask for some advice or support around those issues, there wouldn't be much point in having a forum if people were limited on what questions they could ask!
As you have found, we too have found that there is indeed much conflicting advice given by many health professionals on numerous issues, diet and self monitoring being a couple of the most contentious issues.
I think the general consensus of opinion here is that it is indeed trial and error regarding our health. Many who aren't prescribed test strips buy them to initially find out what foods are causing blood sugar rises and therefore know what to avoid. After a period of self testing many are confident about their blood sugars on a daily basis and don' tneed to test as much.
Much of the NHS Diabetes care is standardised and it is doubtful there will be a change in thinking there, so from a personal viewpoint, I aim to be pro-active and manage my diabetes myself as much as possible.
I have simple aims, to keep my sugars within a reasonble level (for me in the 6's and possibly low 7's) and to be aware of my health generally in case of any complications.
It seems to be working ok so far.
There are plenty of folks here who are type 2's on insulin who I'm sure will be more than happy to try and advise you-feel free to ask.
