Have you heard of withania? It is an extract of ashwaganda - Indian herb. It gives you deep slow and steady strength and helps many people recover from chronic fatigue etc. Get it from Medi-Herb (Australian) at health food shop with a naturopath. Or you can try the good trustworthy people at Herbosophy in WA. Bitter herbs heal us, espec after years of standard Aussie diet and its sugar laden processed fake foods we eat just to feel full.
mediherb.com/contact-us.aspxDon't give up bro. Keep searching for deep natural cures and avoid all the toxic drugs drs try to shove down ya throat for a quick fix. They are like mechanics who just tell ya to turn up the radio and just be happy when your car is making horrible noises from the wheel bearing LOL. IMHO you should avoid the Clot Shot right now until you get your health sorted.
MRIs are a very shallow crude test that very frequently are used by insurance drs to tell you that there is nothing wrong. BS - you know when there is something wrong in your brain! have you had a SPECT scan done? they inject some stuff into your veins then you have a special brain scan that reveals if you have any hypoperfusion (low blood flow) amongst other things.
If you can't exercise or walk then at least keep stretching exercise every day. Keep the blood moving as much as possible. this book is a good read - Dr Kharrazian USA

Have you tried inclined bed therapy?
inclinedbedtherapy.com/Correct breathing techniques can help reset you vagus nerve and heart like nothing else can. Deep diaphragmatic breathing with gutteral exhalation ten to twenty times once a day does wonders for your blood cells and detox rates. It is the lower portion of our lungs that does the detoxing - exactly the part we don't use when stressed out ans doing shallow breaths up in the chest area only. Proper breathing helps the red blood cells relax and separate as opposed to clinging together like scared little people after a traumatic shock like blacking out. Traumatic events like that can leave your body in a fulltime emergency mode with your adrenals working 24/7 when they should only be used for short bursts. We need to reset our bodies after such chronic trauma events like you have had. It may take a lot of effort but it is worth it in the long run to reset naturally. Im sure you will find your way back to health with some expert natural guidance.
