My stance? I'm of the opinion that you are a sandwich short of a picnic. Want a second opinion? ... ok, your paranoid delusion disorder (or Psychosis) could have been brought on due to a physical/medical episode, but could still be treatable by Antipsychotic Medication, or possibly through psychotherapies such as Cognitive-Behavioural Therapy (CBT). Either way, I hope you get the help of which you are so badly in need.
One more thing ... don't forget to check in your closet and under your bed before you go to sleep tonight.
