Mental health

My hubby’s assessment talks a lot about him not looking anxiety does not have a diagnosis of depression.... that he refused a cognitive assessment.......my question is.... that he does suffer with low mood and anxiety ...and this is often seen in him being angry and irritated and no motivation ... he is old school and feels he would be stigmatised if he admitted he was depressed, have suggested many times that he should speak to his GP he still refuses. He has been offered a cognitive assessment and to talk to a psychologist by his neurology team because they see an assess him as struggling, but he refuses, again that type of professional help is just to alien and I believe he is frightened. Should I try and put something about this in his reconsideration letter (with his permission of course) he may say no.
