Everything about mental illness is not pure emotion like something you can handle by lifestyle and better thinking. Like OCD and hallucinations I'd rather see as illness than as "emotional problems" and I think it IS an insult saying your brain bombarding you repetitively with weird thoughts like a dang hail storm, is emotional problems.

I can see how emotional problems more have to do with those diagnoses where emotions are the main factor. But ALL mental illness is NOT like that, sometimes the emotional distress is byproduct of the thoughts/hallucinations/obsessions.
