Does a alcoholic of 4 yrs and in a severe depression for all that while ending up in rehab, now still is depressed and still drinking need medication?

Dual Diagnosis: It sounds like you need to be treated by a psychiatrist and/or program comfortable with handling people with dual diagnoses: alcoholism and mood/personality disorder. From your list of medicines and conditions, you have a complicated mood and/or personality problem which drinking alcohol will destabilize further. Medications may be helpful and even life-saving for some of your symptoms.
