OK. No it's not depression. It is because what they are doing isn't giving the results they wanted. It gives results that create enormous stress.
That doesn't mean the actions weren't the underlying need for W. This was something she decided but the situation with S has been a consequence she didn't envisage. It creates stress.
W is stressed not depressed. As a result it's aging her and there is nothing she can do.
I doubt it's a defence of yours, it's an observation and real. She is aging in front of your eyes and it is unlikely to reverse.
