Welcome to the forum
I am so sorry to hear that you are struggling with your diabetes, tell what are your bg readings like and what is your diet, do you restrict carbs?
I had neuropathy for a while, I wasnt able to walk, no feelings in my legs up to my knees and had to use a wheelchair, after a very serious and drastic lifestyle change I gradually recovered and am walking normally now, I have been very lucky there.
I dont know very much of Charcots foot, one of my now ex-colleagues developed the condition and I believe this has improved over the last year; he had to wear a moonboot style contraption and use crutches which was very inconvenient indeed, he found out about a company called Dorset Foot Orthopaedics and got a very interesting SAFO, it is expensive, I think over £2000, so he applied for funding with his hospital consultant and GP backing and this was successful so it might be worth for you to look into it, discuss with your medics, this walking aid may be suitable for you too??? I know it certainly made a lot of difference to my ex colleague.
Your local PCT will recognise that it is important for you to go to work, so they might just agree funding for this, esp if you have the backing of your doctors.
I enclose the link for further information, I hope it is not getting deleted though as it may be seen as a commercial advertisement I dont know

Its very important that you keep your bg steady and at the level of a non-diabetic, you may also need supplements, but they would not work on their own, control of your bg is the most important.
I hope you get all the support that you need and that you can get better again, although progress would be slow and I am not making promises but surely I cannot be the only one that can recover from neuropathy so there is hope isnt there?
All the best
Karen
