I have an eating disorder, pica, and crave/eat paper and cannot stop! What can I do I've tried everything?
Seek consultation. As previously noted this can reflect developmental issues, but also sometimes medical issues. Its more commonly seen in children. A thorough medical and probably a pediatric neurological consult would be well advised with further follow up with psychiatry and maybe a clinical psychologist specializing in pediatric or health psychology for behavioral interventions.
What have you tried? Certainly counseling along with appropriate medication is a good idea. In children developmental disorders can be associated with pica, in adolescents depression and substance abuse are often part of pica. Pregnancy may have pica associated with it causing cravings for clay or starch. Iron and zinc deficiencies can lead to pica. Anorexia nervosa, autism and schizophrenia can also. Keep trying.
