Experiencing a longing for Wheein during a period of absence and lack of her content.

I miss Wheein, I think I'm wheeinsick

Whensick

Longing for an experience that is no longer possible.

Comparable to the feeling of 'HomeSick', but for a specific time and place, not just a place.

He was whensick when he remembered life in his 20s.
