Victoria, welcome to the forum.
Of course you are depressed, who wouldnt be in your situation. I think if I found myself in your situation I would ask for a second opinion and a third at the very least.
I know that unfortunstely for some reason there is often a delay in diagnosing charcots foot, it sounds like you have any grounds for medicsl negligence?
Was your prothesis taken away so thst you are basically forced to rest the other leg, presumably in an effort to ease any pressure on the ulcer and allow it to heal, hopefully, goodness I am praying for you Victoria.
You hsve shown remarkable courage and strength, becoming mobile after your amputation and learning to walk without a stick, obviously you are a fighter.
Are you allowed to exercise at all, I mean your upper body and arms? And what are your bg levels like? I would have thought that some exercise and keeping very tight control of bg levels could possibly help to heal the ulcer on your foot and help prevent further complications. Can you have manuka honey dressings on the ulcer or leeches which are used in some hospitals on patients with slow healing ulcers.
A while ago we had a post from a very concerned relative of a lady with diabetes, also facing an amputation, she later reported that the leg was saved at the last minute. Here is the link

I truly think that anyone in this forum reading your post will want to offer their support and encouragement.
Please let us know how we can help, how things are going for you.
All the best
