The thing that I am really going to remember from psychology (partially because I'm reading other books that also make this point) is that it's really hard to tell how far is too far, especially with mental disorders. All mental disorders are on a spectrum, and it's so hard to define where the line for the mental disorder is. That is, it's hard to tell what's "normal" and what's a disorder. I'm going to remember this primarily because a lot of my maternal side of the family has been diagnosed with one mental disorder or another. I have been diagnosed with several different things over the years, and those diagnoses have often been changed by the next mental health professional I went to. Even with the DSM-IV, it's still hard to determine the borderline cases and whether they have the disorder or not. This is so crucial to the patient because it can mean entirely different treatments are available or that the patient can get assistance with dealing with their symptoms only if they are diagnosed the "right" diagnosis. If someone is diagnosed with depression, they won't be able to get as much help as if they are diagnosed with bipolar disorder, even if they have the same symptoms. I find this frustrating, because we should really be looking at whether the person needs help, not whether their diagnosis needs help.
