Hi Came across your message just now by accident. Hope you are better but if not.... just wanted to say, have you been checked for autoimmune disease? There are quite a few of these illnesses, but they often cause extreme extreme exhaustion - it's like being thrown into extreme old age without warning - you basically just keep falling asleep, can't get up the stairs in one go, memory non-existent...etc. Did by any chance your mum, grandmother, aunts, have thyroid disease or unexplained illness? Doctors very very bad at diagnosing autoimmune diseases. Can be very few other symptoms, or fleeting symptoms, which they can always write off as something else. If you are persistently always exhausted and can't do the things that your same-age partner or friends can do, can't get anywhere suggest you go to private GP and insist on tests, particularly for PBC - primary biliary cholangitis - get the AMA antibody test. Good luck.
