You are more or less in the same predicament that I am in, except it's my knee...
You may want to reconsider the fast and think about a "Mono-Diet".
That's from the KY TT manual.
One of my KY teachers adviced me to take up this banana diet which rebuilds torn tissue and removes drug deposits... (considering my knee he said.) Which would seem to be a good pick for you as well. Considering our similar predicaments.
No expert here, would be my first go on a fast as well... And will be getting tips from the teacher when I start it on next months full moon.
I can write the diet here:
This diet should be in your price range. You can't get any cheaper than this. Great for your broke ass!
You can do Half the diet, which was recommended for me... (7 days bananas, half day off, 14 days of beans and rice...)
I have the books recipes for Yogi tea and the mung beans & rice cooked with vegetables if youd like them aswell. But you get the picture.
I got that same thing with the body being fragile as shit as well. And alignments being poor...
Problem is insufficient CHI in the "etheric body". Your "inner structure" is fucked up which makes the body "empty" and sloppy. Also because it's the ankle and trauma there (legs) is cutting up much of the chi that would going up and down the leg normally. Which is a factor you havent been that grounded and "physically aware" for some time now. So grounding and getting chi trough the ankle (slowly and safely) should be your main focuses energetically. All chi gung does this and develop inner structure, You should do some standing in the basic chi gung stance (wuji stance) which is most neutral and therefore most relevant for overall healing (static standing practices lso develop inner structure the fastest) but what comes to mind is B.K. Frantzis's "Dragon & tiger medical chi gung". I think he has some material out already conserning only that practice. But what you can also get is "The CHI revolution" which has the practices I thought would be for you from D&T (Includes moving the ankles) and it shows the basic stance I was talking about.... It also works the acupuncture meridians people are so certain about in this thread.
You might also run your hands over your legs at the end of any chi gung session. Don't know how to describe it in any better words.
Meditation should be breath based. Plenty of breathing (outside of meditaion too) as it cleans, brings chi and connects you to the body. Making it easier to find the energetic trauma in the ankle and elsewhere in the body.
You might also want to look up on some good reiki guy and tell him to focus on the ankle and first chakra.
The major healing will happen beyond the physical in your chi so the diet isn't going to be the "cure". it will help. But healing the actual trauma should be your end goal in the long term. And feeling the trauma will be somewhat painful. But you will recognize it as being energetic. Be easy on your ankle.
TAKE THE MONO DIET INSTEAD OF THE FAST MOFO. IT TOOK EFFORT TO WRITE THIS.
