Which are some of Odysseus's internal conflicts in the Odyssey?

One suspects, though it's never explicitly mentioned, that Odysseus is in conflict with himself when he descends to Hades, the land of the dead. There, he meets with the shades of family members and former comrades-in-arms, such as Achilles. It is the appearance of one such family member, his mother, that appears to cause Odysseus no little conflict with himself.
Odysseus tries to embrace the shade of his mother a number of times, but each time he does so, his mother's shade immediately vanishes, only to pop up elsewhere. As we can imagine, this causes our hero no end of grief, which in turn generates an intense internal conflict whereby Odysseus struggles to accept the sheer finality of death. Odysseus still loves his mother but somehow must overcome his internal conflict and accept the finality of death before he can truly be at peace over the fate of his mother.
