Can being unusually happy mean one is sick like delirious?

In brief: Rarely

People with mania are usually more over-active than happy, and euphoria usually (whether from getting high or mental illness) look pretty quiet from the outside - a person is more tuned out than excited.
A delirious person is confused and disoriented. Being unusually upbeat in a very bad situation can be denial, or can just be a way of coping. If concerned, consult a mental health professional.
