Yes feelings can be recovered. I had none up until a few years ago and endeavoured to get them back. Now I can feel negative emotions, but not positive. But apparently if you have a good therapist therapist that knows what they're doing (and is patient), eventually you can get the good feelings back too. Thats what they tell me! I figure it makes sense because regardless of whether feelings are negative or positive, they are all FEELINGS so what applies to one also applies to another.
