"I must write you a line or two and see if that will assist in dismissing you from my mind for ever so short a time. Upon my soul I can think of nothing else - I cannot exist without you - I am forgetful of every thing but seeing you again. You have ravish’d me away by a Power I cannot resist; and yet I could resist till I saw you; and even since I have seen you I have endeavoured often “to reason against the reasons of my Love”.
I can do that no more - the pain would be too great - My love is selfish - I cannot breathe without you."
- J. Keats’s letter to Fanny Brawne, 13 October 1819
