For all that Marianne would like to believe that no one has her feelings or suffers as she does, there are others who are suffering deeply in love.

I feel so sorry for Colonel Brandon when the Dashwoods first arrive in town and he comes to visit them that first evening.
Marianne, expecting Willoughby, nearly throws herself into his arms and then in great shock immediately leaves the room :-(

Elinor feels "particularly hurt that a man so partial to her sister should perceive that she experienced nothing but grief and disappointment in seeing him. She instantly saw that it was not unnoticed by him, that he even observed Marianne as she quitted the room, with such astonishment and concern, as hardly left him the recollection of what civility demanded towards herself.

But, typical of the colonel, he is not upset for himself--he is concerned on Marianne's behalf, and wants to know if she is ill.

Elinor, too, directs her thoughts to Edward, feeling sorrow because "If her case were pitiable, his was hopeless," and "she wept for him more than for herself" considering what his future life will be like.
