Things are far harder for me nowadays. Although I try to do "normal" things , I get exhausted very quickly after mental or physical things. This must be a combination of getting older and my 2013 stroke. My stroke after-effects cause me to be giddy almost all my waking hours. This is a "hidden disability" that few can see or understand.
As I have said many times, never judge a book by its cover. Many people suffer in silence whilst casual observers can see nothing wrong and mistake exhaustion for laziness.
