I absolutely do, but I think more in the situation my mother is in.
She is her father's carer. He's 89, has dementia and other numerous ailments which make him caring for himself, rather tricky.
Mum, has been "depressed" (not in any way implying it doesn't exist, my mother's situation is a little different to most), for about 20 years. Is addicted to anti-depressants, sleeping pills and alcohol and is constantly telling me how she spends most of her time, out of the house avoiding her father.
IMO, she should have had an assessment done to make sure she was able to cope with all aspects of caring for him, by an independant psych, for Centrelink to "accept" her as a fit carer. (Centrelink, because apart from them, really, who else knows or cares that she is a carer)
I know most people in an industry such as this, would be taking the appropriate action into their mental health, but some don't and I think there should be assessments done (with or without disclosure of mental health status), to determine whether a person is able to "cope" in the chosen proffession.
