Looking at the relative burdens and tasks of Frodo and Sam, we might be underestimating the toll of the Ring-bearer, which, for 99 per cent of the time, is Frodo.
The Ring is slowly poisoning him and invading his mind, more so that Sauron has risen again and his strength in the world is waxing. Plus, the terrible wound from the Morgul knife in his shoulder. Bilbo never faced anything quite like that, and Sam only for a short time.
I don't think Frodo is in any condition to help others much. He has enough problems rising up every morning and walking again.
I think at its worst, it might be something like a combination of cancer and schizophrenia (or withdrawal symptoms). Weakness, unability to rest, intensely intruding mad thoughts, despair.

BTW I just love nerding out on HN.
