I spent a lot of time compiling forum posts a couple years ago of people who improved. Most of them improved after 6 months, one guy recovered completely around 3.5 years. One person took 10 years. It seems it can improve at any moment.
@Ngo13 I understand, I gave up on hope probably a year ago. It seems to be part of the road to acceptance as I was making no progress in that respect when I still held on to hope.
