My husband's been wonderfully supportive and I'm now back on the meds. In a few days I'll be my old self, catch up on some work and have fun writing again. I'll probably even smile, be goofy and such.
Take care. I know I will :-)

Writing With Depression
I have so much I could blog, post, write, contribute and just can't get myself to do it. I'm suffering from depression. Like a dummy, I let my anti-depression medication expire. I felt I could keep it under control with vitamins and the like. I've tried it before, without success. Why would I try it again? That's part of the cycle of depression. I should have known better but I wanted to be strong without the medicine. Duh.

Science Daily — Brain imaging has revealed a breakdown in normal patterns of emotional processing that impairs the ability of people with clinical depression to suppress negative emotional states. Efforts by depressed patients to suppress their feelings when viewing emotionally negative images enhanced activity in several brain areas, including the amygdala, known to play a role in generating emotion, according to a report in the August 15 issue of The Journal of Neuroscience.
"Identifying areas in the nervous system that correlate to pathological mood states is one of the pressing questions in mental illness today," says Carol Tamminga, MD, of the University of Texas Southwest Medical Center. Tamminga was not involved in the study.
Tom Johnstone, PhD, of the University of Wisconsin, and colleagues there and at Tufts University studied 21 adults diagnosed with major depressive disorder and 18 healthy subjects of comparable ages. Participants were asked to view a series of emotionally positive and negative images and then indicate their reaction to each one. Four seconds after the presentation of each picture, participants were asked either to increase their emotional response (for example, imagining a loved one experiencing what was depicted in the image), to decrease it, or simply to continue watching the image.
During the test, a functional magnetic resonance imaging scanner detected changes in neural activity. Johnstone and his colleagues also recorded levels of emotional excitement by measuring pupil dilation.
The data showed distinctive patterns of activity in the ventromedial prefrontal cortex (VMPFC) and the right prefrontal cortex (PFC), areas that regulate the emotional output generated from the amygdala. The VMPFC is compromised in depression, likely because of the inappropriate engagement of right PFC circuitry in depressed individuals.
"These findings underscore the importance of emotional regulation deficits in depression," says Johnstone. "They also suggest targets for therapeutic intervention."
According to previous research, normal interaction between the amygdala and the VMPFC may underlie the proper adaptation of levels of the stress hormone cortisol on a daily basis. These levels do not vary as widely in people with major depressive disorder; future research may now be able to clarify the mechanism that underlies this aspect of depression. It could also examine the possibility of using measurements of activity in the amygdala to predict the effectiveness of treatments for depression such as cognitive behavioral therapy.
The work was supported by the National Institute of Mental Health, part of the National Institutes of Health, and Wyeth-Ayerst Pharmaceuticals.

Thank you very much for this. I had to read it a few times to understand it but I get it now, LOL. I have a book on cognitive behavior therapy. I better dust it off and start reading!
Take care.
