I agree DB, as a good start. I would add histrionic Borderline Personality Disorder with grandiosity.
The above link to cafemom is VERY enlightening! She claims her husband got a doctor to prescribe Prozac to her (there's that blaming again) along with other anti-depressants and an ANTI-PSYCHOTIC.
I can tell you that a physician would NOT prescribe an anti-psychotic medication for ordinary run-of-the-mill depression. Psychosis is very very serious.
Borderlines are known for rejecting the diagnosis and refusing treatment, insisting that it is OTHERS that are messed up, not them. This is looking pretty familiar. If this is a person who SHOULD be on anti-psychotic medication, it certainly could explain some of the delusional behavior we have seen. Just sayin'.....
