Avoiding depression: is a matter of optimizing your environmental conditions. You are doing well with the vitamin D and sun exposure. Eating a varied diet of primarily colorful, whole plant based foods will help. If they are healthy enough to do so, people with SAD may consider daily mild to moderate exercise after consultation with their doctor. Avoiding alcohol is also a good idea. Hope this helps!
