Mitochondrial myopathy. Simply put, I do not produce enough energy to keep my body up and running. There are many possible causes; in my case, it is a single large scale deletion in my mitochondrial DNA. Symptoms are varied. In my case: extremely weak eye muscles (I have both ptosis and diplopia), intermittent fatigue, mild aerobic exercise intolerance and hot intolerance. From a scale of 1 to 10, being 10 the worst, I rate myself at 3. So, I am doing fine. Watching what I eat, doing some exercise and controlling stress made a big difference in my quality of life (going from 7 to 3)
