If the same if for other activities, not just work, you might want to be checked for chronic fatigue syndrome (CFS, similar to long covid). It can be like having a permanent flu in some ways (exhaustion, brain fog, non-restorative sleep, sensitivity to stimuli). Many doctors may have been influenced by a now-debunked study that claimed that gradually increasing exercise or getting CBT was the fix, but now the CDC, Mayo, UpToDate, and others seem to have better information. One source is batemanhornecenter.org . Diagnosis (at least in the past) involved eliminating other diseases and depression. Also just an idea: finding what you can do might help understand the situation.
