I am single & have zero energy for partners or children after 4 years of ME/CFS. I used to travel the world, teach internationally & research/grant write in USA: my REMAINING energy goes to doctors, research on ME/CFS, family, but I live alone in a quiet dark, cool bedroom, can only tolerate liquids, am exhausted by speaking, writing, thinking...I think if I were in a relationship it may not have survived the ravages of this disease.
