Johnboy - I would urge you to try some cooking from scratch. The Jamie Oliver youtube clip I posted the other day show it doesn't have to be complicated to produce a meal. Following a recipe is just like following the instructions on a ready meal. OK, there may be a few more steps, but if you cook sensibly, you can cook several meals at one time, and freeze some for later. And it's much, much cheaper than buying ready meals.
You've already mentioned (I think! Correct me if I mis-remembered) that you enjoy casseroles. If you have a slow cooker, or can acquire one; a quick google on Argos shows a family sized one for under £15, you can make a batch of casserole with a little bit of prep and then just leave it cooking all day, looking after itself. You'll be astonished. If you absolutely cannot bear to spend time chopping veg, you can buy ready prepared veg at all the major supermarkets, although you're obviously paying someone else to do the chopping.
I bet if you started a thread, with a list of things you like to eat, asking folks for either recipes or alternatives, I'm sure you would get a decent response. We all started somewhere, but you need to start starting, rather than talking about starting. The thing about doing something tomorrow is that so many tomorrows don't arrive, because tomorrow there's a brand new tomorrow just around the corner.

Doing is the key here. If you do something and make a mistake (your blood spikes), at least you then know something about that food. Doing what you have always done will result in the same outcomes you have always got. Don't waste this golden, newly diagnosed, opportunity.
