So what mental illness...
is being depicted here, in Wyatt's case?
shareLooks like schizophrenia to me.
shareAgreed - possible paranoid schizophrenia but then psychosis is a feature of other mental illnesses, as well - e.g. it's possible with bipolar, BPD and potentially something that occurs during a complete meltdown. There will be people who report a psychotic episode at some point in their life who don't necessary meet criteria in the DSM to make it specific to any one disorder.
shareI don't know, it's just a movie but a great story none the less.
