About 8 years ago, I was knocked for six by Chronic Fatigue Syndrome/ME. It took me off work, limited my activity, and was utterly awful. Thankfully, after almost a year of careful eating, exercise plans and increasing activity incrementally, I got over the worst of it, and moved on with mmy life. The only time I even remember that I have it is when I'm ill, and the primary symptom is feeling run over by a steamroller.
The last few weeks, I have been struggling with a cough I couldn't shake. The cough is now gone, but in its place is sheer exhaustion, poor sleeping, really bad stomach pains and bloating, terrible reactions to alcohol, and a general inability to remember my own name.
It's been such a long time since I suffered properly that CFS didn't even cross my mind. It's only now that I re-checked the symptoms, and I tick virtually every box... 
Not certain anyone can really help (although, if you have advice on how you handled it, I'd love to hear it!), but I just wanted to write it down and have a little pity party...
