Female, 31 year old, with long history of depression starting in early teens, came to a psychiatrist(my colleague) with main complaint of incessant crying and worsening agitation. She had symptoms of severe anergia, slow thought processes, short-term memory loss, and forgetfulness, but she had a good sleep everyday. She suffered multiple crying times daily and admitted that she wanted to isolate herself from everybody.
She also had irritation and agitation with daily panic attacks but had no psychosis. Her depression began in early teens with progressive worsening gradually. What is to be suggested by experts on psychiatry here?
