I am not going to argue with your C, she does sound like *something* is wrong with her but maybe it's not depression but more of an internal flaw she can only correct.
If she started seeing a psych in 2008 something should have changed by now if she is following the care plan. Not only has nothing changed but her behavior has gotten worse.
Like you said - this has been on ongoing problem for all the time you have known her... nothing is enough, she always wants more, she constantly needs tangible stimulation (bigger house, more children, new job and so on). When an adult can't just "be" there is something very wrong inside. Is it depression? Maybe. I tend to think it's more of a character flaw or some sort of internal struggle to try and create an ideal life when in fact if she would just stop and take a minute she would see what in front of her is ideal. And if she has childhood issues (who hasn't?) that makes sense.
I have a friend who had a really tough childhood. It was bad. She is now married to an amazing man, they are very financially comfortable, she has a terrific little boy and has created her own family. But she is always running, running, running and scheduling herself and her family to the point of exhaustion. Why? Because when she was growing up she had NOTHING.. no extras, no vacations, no lessons, no security... NOTHING. She is terrified that if she stops moving and just enjoys what she has (which is all she ever wanted) somehow it will be like her old life. That is not depression. That is an internal flaw/struggle that can be addressed but it's not depression.
People that always need/want more and will destroy a family to get it are not depressed. They are *something* but depressed isn't it.
