This attitude may very well be one of the root causes of her problems in the first place.
Long ago, I was treated for clinical depression. Looking back at it, I was just feeling sorry for myself at the time. Everyone else I have met that is being treated for depression or anxiety is skirting the real issues in their lives, which are almost always self-inflicted. Instead of dealing with the real problem, the psychiatrists love to hand out pills and string these folks along. I quit using the Prozac "crutch" and dealt with my problems head-on. I've never been happier than I have been these last few years.
As a side, my MIL is moving to Texas and her Dr. has put her on Prozac for nerves. Since starting it she has lost weight and seems a lot more flighty. I don't think she even needs it. Of course she is going to have anxiety. She is making a big move. But I think the drugs are making things worse.
