Delirious vs. Ecstatic
Delirious and ecstatic can both describe extreme happiness.
However, ecstatic is more directly associated with intense happiness or excitement. Delirious can also have a serious meaning involving confusion or altered mental functioning.
Example:
She was ecstatic about her promotion.
This clearly means she was extremely happy.
He became delirious during his illness.
Here, the meaning is very different: he became confused or mentally disoriented.
Delirious vs. Euphoric
Euphoric describes an unusually intense feeling of happiness, excitement, or well-being.
Delirious can describe extreme happiness, but it can also describe confusion.
Therefore, euphoric is often more precise when you specifically mean intense positive emotion.
Delirious vs. Frenzied
Delirious can describe extreme excitement, while frenzied emphasizes uncontrolled or chaotic energy.
Example:
The fans were delirious with excitement.
The focus is on their extreme excitement.
The fans created a frenzied atmosphere.

Delirious vs. Confused
These words overlap only in certain contexts.
Confused simply means unable to understand or think clearly. Delirious can imply a much more intense state of mental disturbance.
Example:

But:
The patient became delirious after developing a high fever.
The second sentence describes a more serious condition.
