First of all Welcome to The Downs Fortheshire......I think if Frodo was alive today, he may well have been diagnosed with PTSD. In the First World War, Tolkien may well have witnessed Shellshock, no-one ever really recovers from the kind of trauma that Frodo lived through, in war someone always suffers, there is no going back to the good old days after The Two World Wars, things have changed, yes the evil has been destroyed, but you cannot wipe out the memory of it by wishful thinking. The bodily pain he suffered was more to do with being hurt by Knife, Sting and Tooth, yet the loss of the Ring would have played on his mind, maybe like people who have taken hallucinagenic drugs have flashbacks, Arwen recognised this by giving him the white gem 'Where shall I find rest' was his cry. He seemed at times to be going through a depression, some have linked this to the same thing that happens in wars, where soldiers expect to die but don't. Frodo did not live out his life in the Grey Havens, he went to Tol Eressea, an island in the Bay of Eldamar which was off the Coast of Valinor. Taking into account of Bilbo's age, he couldn't have lived much longer, leaving Frodo the only hobbit west of the sea. Sam went west many years later, Frodo's only companions would probably have been the elves, the companionship of hobbits would have been missed even in The Blessed Realm.

P.S Bilbo is already 78 yrs older than Frodo and would not gain more life for being in The Undying Lands, probably the opposite.
