@mangeurdenuage There could be some initial physical cause, but the stress that you and your family members have been under the past year or more could cause physical damage.

My middle son's wife was told by her doctor to quit her job if she wants to live. The doctor said the stress of that job was causing her body to attack itself. So now they have the stress of trying to survive on half the income. ( #'s two jobs pay just about as much as her one job was paying. )
