He is physically okay now and have severe osteoarthritis along with weakness on left part of the body due to stroke. Now a days he became arogant and sometimes he is feeling like something happening to him which cannot be expressible and feeling like getting cry. His wife passed way long ago (2012). We tried multiple ways but no luck. He always thinks about money or something. Since Work from home come to end, we have left no option other than keeping him in retirement home. however, before that also he was suffering with below problems 1. feeling like getting cry for unexpressible reasons, ache near neck and above back brain 2. lonely, depressed Please advise.!
