Hi Copia.
Symptoms come from somewhere...not from nowhere. But reasons why are less important than finding ways to alleviate invasive symptoms. Words are powerful things....labelling a person as...or labelling oneself as 'hypochondriac' is counterproductive in my opinion. Having your severe depression treated by a caring and invested physician first and foremost is your first step...the why and wherefore can maybe come later.
I wish you all the very best moving forward Copia...Welcome to PC
