Question: What is clinical presentation of the Gardner-Diamond syndrome?

Context:
Antidepressants were prescribed by the psychiatrist that not only cured the depression with time but also the bleeding episodes which were actually related to child's depression (Gardner-Diamond syndrome or psychogenic purpura). 
Psychogenic Purpura (Gardner-Diamond Syndrome).
Psychogenic purpura, also known as Gardner-Diamond syndrome or autoerythrocyte sensitization syndrome, is a rare condition characterized by spontaneous development of painful edematous skin lesions progressing to ecchymosis over the next 24 hours. Severe stress and emotional trauma always precede the skin lesions. 
Gardner Diamond syndrome is a rare condition characterized with painful ecchymoses in different parts of the body and cutaneous and mucosal hemorrhages. The etiology is not known fully and psychogenic factors are thought to be involved. 
Psychogenic purpura, also known as Gardner-Diamond syndrome, is a rare, distinctive, localized cutaneous reaction pattern mostly affecting psychologically disturbed adult women. Repeated crops of tender, ill-defined ecchymotic lesions on the extremities and external bleeding from other sites characterize the condition. 
PPDDM includes impulse control disorders, obsessive-compulsive disorders, factitious disorder, factitious disorder by proxy, self-mutilation, delusions of parasitosis, psychogenic purpura/Gardner-Diamond syndrome, and cutaneous sensory disorders.
Psychogenic purpura (Gardner-Diamond syndrome) is the occurrence and spontaneous recurrence of painful ecchymosis following emotional stress and minor trauma.

Gardner-Diamond syndrome (GDS) is an uncommon disease clinically characterized by a wide spectrum of psycho-emotive symptoms associated with painful ecchymoses/purpuric lesions and positivity of auto-erythrocyte sensitization skin test.
