You might try a low carb diet. It definitely reduces the hunger you feel from eating less, and it's definitely more compatible with depression.

Alcohol-wise, if you are drinking half a bottle of vodka a day (for example) that's about 750 calories just from the alcohol, so that's an impediment to weight loss. If you can manage with half that, not so bad. If you are drinking sugary cocktails, that's WAY more calories, plus the problematic carbs, which basically make you hungrier. If you can decide you like something like diet tonic + gin/vodka, or meyers's and diet coke, or even dry wine, well, that's something!

Low-fat calorie-restricted WW/JC-ish diets are pretty difficult for men to maintain and are often hugely difficult for women to maintain.

Just my $.02.
