I think I understand something of your point of view. It is a little hard to be sympathetic for someone who had many resources to sort out what was a relatively minor problem.
As others have pointed out, she does acknowledge this privilege and so on. Of course, yes everyone's experience is valid and what worked for them might work for others.
I guess part of the problem is that 'depression' is like a long road. Some people are only a little way along this road, some are all the way to clinical depression and beyond.
I can't quite imagine what my current mood or mental state would be like if I did not have the financial resources to at least mitigate or forget about things for a while.
To switch metaphors, some people are in a shallow well and say 'I just climbed out!' while others are in a much deeper well, with slippery walls, and weights attached to thier feet (or something).
