Personally, I feel these symptoms present themselves different in not only the individual but the situation the individual is living in. I guess if a specific type of hallucination or delusion repeatedly presents itself, it may be possible to diagnose that patient and further classify the type of symptom or illness it is. Then, at that point, these symptoms can be compared and worked through. Also, it is my personal opinion that there are internal and external factors that are difficult to distinguish AND much overlap between the different disorders. I feel that diagnosis is only one component towards healing and progress, but also these specific symptoms may be most difficult to share because many of them are fear based but could also be from external or physical reasons…. or both.
