I have ME/CFS for 8 years. I work full time job and have a demanding little one. I exercise and have been all the way I have been sick, sometimes that means 3 walls push ups, up to walking 3 miles. One day I am all up and running and next day I cannot get out of bed. I am lucky to have a mild version (lost about 50% of my energy) and everyday is a challenge. But no it is not being afraid of exercise. Is the inability to produce energy on demand to do the most basic things: Brush teeth, stand to eat, drink water. Your energy production changes from day to day.

I have low NK cells, Low T cells, Viral reactivation. I got proper treatment: Antivirals to treat infections. Midodrine + Florinef for Orthtostatic intolerance. I am at 7/10 now.

If you have CFS pls be treated appropriately. Check your immune system and you will see the abnormalities: Lymphocite subset test, check reactivations: Viral: hh6v,ebv,parvo, coaxsaxie, CMV....

I do not feel like having the eternal flu anymore. I am glad I didn't let LAZY doctors tell me there is nothing wrong w me. When I saw the right ones: Immunologist, Electrophisiologyst and got the right tests : Check NK, Tcells, B cells, Tilt Table test....

I had 3 remissions, which I crashed on heavy exercise the 3 times (tried to run, too much weights...) So I know you have to keep moving, too much is bad. Listen to your body.
