this is best left for you to discuss with your doctor..there are different TYPES of depression...(reactive, major)...no one can guess what treatment would work.
Getting the booze out of your system will help whatever meds you might be prescribed work better. exercise and meditation are natural forms of relaxation that can't hurt you. Considering all the trauma and upheaval in your life, talking to your doctor and getting counciling along with quitting alcohol are the best things you can do for yourself.
If you are prescribed meds by your doctor, be sure they do not have contraindications with any supplements you are taking, tell the doctor what you take vitamins and all. try not to worry, the doctor will monitor your dosage and if it doesn't work well with your body, they can try a different one. (this is common too).
I know you might feel so stressed and anxious this week, but try not to worry too much. take care.
