Ankles are so complex. This is a real problem, and a real trauma. Have you worked with a physical therapist? (my head is thinking tai chi also, for balance)---there are ways to strengthen muscles that can help, I don't know if soft support (ankle "brace") would help, but you need to avoid further damage. I am also curious as to how the injuries occurred.

You have nothing to be embarrassed about, you have a problem to deal with.
