My recent improvement is largely due to playing tennis. I bought solo tennis and almost play every day, each time just about 10 - 15 minutes. I have to use my arms a lot, which was what I lacked during the past years or decades! This exercise finally balances my body movement, improves my blood circulation. I almost felt the benefit of it in a couple of days' after playing tennis.
Also, I started wearing sleeveless shirts during outdoor activities, which makes me receive lots of sunshine. My sleep is better! Of course, melatonin!
So looking back, my strategy worked! First, diet and sleep, let my body recovered from extreme lack of nutrition; second, mild exercise like stretch and walking, little by little, to increase bloody circulation; third, expanding my exercises to full body, to build muscles (which I lost during my chronic decades!).
Physically, I am feeling quite well, about 80% recovered. I must congratulate myself.
