Hi I had gone through your query. Extreme depression or severe depression require extensive indoor psychiatry care. Depression can be treated with multi modality approach depend upon symptoms severity. Mild to moderate depression require medicines and counseling. Severe depression can be treated with medicines and ECT. ECT means electro convulsive therapy is the choice in severe depression with suicidal ideation. IN medicines SSRI is the choice. Abusive nature may raise the possibilities of psychotic features along with bipolar illness. So detail evaluation is necessary for diagnosis and treatment. Consult psychiatrist and get further assistance. Get well soon. Still if you have query then feel free to ask me directly on http://doctor.healthcaremagic.com/doctors/dr-vishal-garala/68046 Thank you.
