“Is the recovered schizophrenic lost interest?”

I have schizophrenia and I am taking medication. Before, I didn't have the right medicine or not enough medicine, my illness was not recovered. At that time, I had no interest. When I asked the doctor, she said schizophrenia is like this, have no interest. Now I have the right and enough medication, I was recovered. But the doctor's word influenced me, I still feel few interests. So can you tell me is the recovered schizophrenic will lost interest?
