I came home from hospital unable to walk. Bed bound.
After a few months and listening to someone on this forum I splashed out on a rollator. It is this sort of thing.
I didn’t suddenly walk for miles but as I could stand, holding onto the handles let me take a step or two away from my bed, then sit, rest and return.
The availability of a seat made the process easy to control. Eventually I could get as far as the kitchen, make a brew and transport it back on the seat.

So I would say first aim to be able to stand upright. You can hang onto something, no problem, as long as you are able to stay up. Any time you feel rocky stop and just stand.
Next get one of these rollator things with a seat. Practice taking a step or two then resting. Be kind to yourself. Slow and steady wins the race. Holding onto the handle bars I was able to watch the action of my feet and legs. It helped me get used to the process and improved my confidence
Next when I was a bit less wobbly I started to use a walking stick. I can manage without it now but still use it fairly regularly. None of this happened instantly, just be pleased with any small improvement.
Just one last tip. When you are standing keep your nose in front of your toes, it rhymes and helps with balance too.
Oh, and the professionals were very negative about striking out like this. They don’t want to be held responsible for any falls, I suppose.
Well falls did occur, but I wasn’t looking for someone to blame, in fact I was pleased to be making progress and the occasional sore elbow or bum was small price to pay for the increase in confidence and sense of achievement that I gained.
Keep on keepin’ on

Re-reading what you have to say, I am sure you have the strength, the determination, to succeed, it makes me sure that you will make progress.
It is worth making the effort but remember that having a day off might be just what you need. Strive and rest. Be kind to yourself, be patient. Be brave.
My experience has taught me that that what is possible is greater than I had believed. It is only when looking back that I realise slowly, slowly there is worthwhile improvement and It hasn’t always come with a great struggle.
I believe that simply keeping trying you will get results. It might not be instantaneous but things will move forward.
