Your depression seems inadequately treated if your symptoms have been persistent for over a year.
Your medications need to be reviewed by your physician and determine if an increase of dosage or a medication change is necessary.
Reserach shows that a combination of psychotherapy and medications is the most effective treatment for depression.Cognitive-Behavioral psychotherapy is particularly useful for the treatment of depression. You might reuqest a referral for this therapy.
Talk to your doctor about your concerns and treatment plans.
