Hello RUTHB and welcome to the forum!
Here are a few comments for you -
It's very easy to slip into self pity and blaming yourself and saying 'if only...' --
If only I'd smiled at that girl, and said 'Hi' then perhaps.......
If only I hadn't had those nineteen double vodkas.....
If only I hadn't taken that bend at 90mph.....
And so on, and so on
Unfortunately that way lies madness; you can't turn the clock back, so dredge up a bit of that ancient hippy zen, even if you're not an ancient hippy, and remember the cliche 'Today is the first day of the rest of your life'.
There is a lot of advice on diabetes -
The Learning Zone and help boxes on the Home Page
Previous Threads, especially Newbies, Food & Carbs, and Weight Loss
YouTube videos, though as with anything on YT you have to take the videos with a bit of caution
Reversing Diabetes is popular at the moment and has caught the imagination, with books by Drs Roy Taylor, David Cavan, and Michael Mosely, and YT videos
My own opinion is that they are a bit ambitious, and people should get the basics right with a less severe regime first; though good luck to anyone who can manage it
In some ways, you are in a good position to deal with diabetes and Lockdown
I. too , live on my own, though I am retired
You have the run of a kitchen, and can prepare & cook whatever you like whenever you like, and don't need to do different food for anyone else
There is a load of information available on diet & food, but it's not much use if you don't use it
I've seen your Thread about the chocolate drink, and the amount of sugar involved is absolutely overwhelming
Yes, make the changes to your food & diet, but you need to stop drinking the chocolate drink most of all
Here are some of the indoor hobbies & activities that I & friends, male & female, do, and have carried on or have taken up during Lockdown -
Making model planes
Knife making
Leatherwork
Sculpture
Painting
Learning Spanish
Wood carving
Making fancy greetings cards & calendars
Sorting out all my sewing stuff and doing some bigger items
Quilt making
I'm in The Backpackers Club; many people have been mending, overhauling, and reproofing their gear
Sorting & clearing out a lifetimes accumulation of family & household stuff, and decorating the place from top to bottom
Sorting out all their fishing tackle
Improving my cookery and trying new recipes
There must be something you can do to take your mind off sitting around and drinking sugary drinks?
A couple of friends have said that Lockdown is an opportunity to do something they've always fancied, and are determined to have something to show for this enforced isolation, otherwise we'll look back and wish we had that time again
Nothing in the body acts in isolation, and anything to do with blood, heart, weight etc. are all rolled up together
You will probably find that as you reduce your sugar intake and get more exercise things like weight, blood pressure, cholesterol also improve, and your requirements for medication will go down, and you will start to feel better and more lively
In fact many people who have been diagnosed with diabetes take the opportunity to make changes to their diet, exercise, booze, fags, cut out junk food, and all the rest of the healthy living thing - it all has a sort of combined effect, on both the mind & body
As an incidental, although things like olive oil and some fresh veg can be a bit pricey, most people find they save money by not buying lots of junk food
I've seen this comment - 'I'm healthier since I've had diabetes than I ever was before'.
Finally, you could join Diabetes UK
They have an introductory pack, a magazine, and can give you more and better advice on your particular situation
Also useful if you live on your own is to call their advice line and actually speak to someone
