Welcome aboard Carol.
It's not clear whether you don't like to exercise or you have a problem that makes exercise impossible, but I would say that it's great if you can exercise, and it can make a difference to your blood scores, but (and it's a big but), what you eat and drink is far more important in terms of grasping control.
If you can even just park further from the entry/exit at work, shops, cinema or whatever and within reason shun lifts, it's likely you could be exercising more than before. I spend quite a bit of time abroad in the heat and find it so much easier to exercise over there, where I walk and swim every day. In this horrid, cold weather (I don't care that "they say" it's the warmest winter for years!), I find I just want to hibernate.
If you don't already, I would recommend you acquire a a finger prick test meter and strips and start testing your bloods, around your eating regime, so that you can see what affects your bloods most. For most people that will be the obvious things like sugar, sweets, cakes, fizzy drinks, but for many, many bread, pasta and rice are a bit tricky, at least at first.
Once you get a grasp of what impacts your bloods it becomes a whole load easier to work out what you need to do to move forward to an improved life. The immediate feedback is simply invaluable.
Good luck with it all.
