Also, your diet is WAY too low in fat.
Blood cortisol levels for your situation are next to useless unless you have a true adrenal disease. An Adrenal Salivary Index and some basic bloodwork looked at through a proper perspective (ie. tighter functional ranges, not the ones on the bloodwork as "lab ranges") would be necessary and extremely useful here. If you were actually high for the lab range, then you have a significant issue, yet maybe not an "adrenal disease" like Cushing's.
Something to consider if you did have high cortisol levels in the blood in relation to your fracture (cortisol is equivalent to cortisone for all intents and purposes here):

Effect of cortisone and an anabolic steroid upon plasma hydroxyproline during fracture healing in rabbits.
Lyritis G, Papadopoulou Z, Nikiforidis P, Batrinos M, Varonos D.
The effect of cortisone and an anabolic steroid on plasma hydroxyproline (HOP) was investigated in young male rabbits, following operative fracture of the radius. The action of these hormones was studied in three groups of animals, a cortisone (hydrocortisone sodium succinate 5mg/kg every day), an anabolic (norandronolone-19-phenylpropionate 5 mg/kg every other day) and a cortisone plus anabolic treated group. A fourth group of animals served as controls. Plasma HOP was found to increase during the fracture healing in control animals, particularly in the first week and during callus remodelling. Cortisone produced elevation of HOP level during the first two weeks followed by a decrease to low normal values. Animals treated with the anabolic did not present the initial rise but a sustained increase during callus remodelling. When both the anabolic and cortisone were administered, a curve similar to that of cortisone-treated animals was obtained. The initial increase of HOP is attributed to bone destruction and to a lesser degree to synchronous bone formation at the site of the fracture. This catabolic process seems to be enhanced by cortisone and inhibited by the anabolic. When, however, the two hormones are given together the protective anticatabolic effect of the anabolic is almost abolished.
And yes, your testosterone level should be considered low (and that's not even considering what your free test value is, the actual "useful" stuff!). If you were to ignore the deeper issue and get testosterone injections, as soon as you stopped the injections the underlying problem (which likely would be forgotten about until it reared up again) would return.
I have utilized a training approach that has worked well in returning people to feeling well in several months, and it will not involve any medium-to-long metcons at all. Why?

Ice water baths for your foot, 20 minutes, several times a day, would do you much better than hot "plain" baths (which may be causing you to sweat out even more minerals).
Lastly, has anyone bothered to do a vitamin D test on you?
