If you can simply "work on another scene", you are not really blocked. Most of what people call writer's block is just a form of procrastination, and because of this, many people declaim that there is no such thing.
Genuine writer's block does indeed exist and may be linked to clinical depression. Saying it isn't real does not make it go away. Your not having it doesn't make it any less real for those who do.
