My wife seems to be delusional and paranoid. i can't get a hold of a psychiatrist any time soon. is it ok to wait?

I wouldn't wait: If she is acutely paranoid with new onset of symptoms i would not wait. If she has thoughts of harm to self or others than it is a medical emergency. If she needs to be evaluated at the er then they may be able to help you to arrange for a psychiatric evaluation (if she is not admitted).

Seek help ASAP: When a person is delusional (paranoid, for example) it is best to have an urgent evaluation asap. Most emergency rooms have access to a psychiatrist or other mental health professional who can evaluate a person with psychosis. If need be she can have such an evaluation even against her will. Calling 911 or going to your nearest emergency room is a good option if she will not agree to seek help.

No: These symptoms, untreated can lead to more serious problems and repercussions. Take your wife to your pcp or the emergency room if you are very concerned.
