My son has neurofibromatosis type 1. He is 33 and has difficulty staying with any job or getting a job. He was disagnosed with ADD when is was younger and lacks problem solving skills. He applies for jobs, goes for interviews, and doesn't hear from them. He thinks it is because he has fibromas all over his face and arms. He thinks an employer does not want him dealing with customers. What do I need to do to help him?
