The pathophysiology of mood disorders

Don't worry. I shan't quote the journal of psychosomatic research ( from which I have have just navigated away from) I am not going into the signalling networks, the G proteins, nor will I even attempt to elaborate on cellular resiliency. ( Bleah) I shall instead dwell on my current mood which is that of regret having been moody towards the end of the working week. Precipitating factor being just plain ole crabbiness.
