That point of view may consider the Sun to be on the cusp even when its centre is as much as two degrees away from the sign boundary. They may also call other objects (much less than half a degree in diameter) on the cusp despite no part of the object being in the adjacent sign.
I agree with the Shrink Rap doctors. The term âchemical imbalanceâ is short-hand used by laypersons to describe what we canât scientifically explain. We know something is awry in someoneâs brain when he/she shows symptoms of bipolar disorder, schizophrenia or severe and persistent depression. We know chemicals often can help alleviate these symptoms.
But from what I can tell from reading articles on the matter, neither is anyone else. No one has been able to tell what ânormalâ levels are, or how these things affect our emotions. So far, the idea that a chemical imbalance causes depression or anxiety is just a theory. In the more than 50 years of studies, there has been no proof that depression, anxiety, or mental illness is caused by chemical imbalances. On the other hand, it seems to have been disproven a number of times.
