Some of your symptoms look like they could be related to Depression
but I am concerned about your hair loss and bruises which are not typically associated with pure psychological problems..there could be physical reasons for all these symptoms.
(unless you have already been prescribed by an antidepressant which belongs to a group called SSRIs-which could explain your unexplained bruises)
My advice would be to consult a physician first and if there is nothing physical that he can find causing these then consult a psychiatrist
Hope this helps.
