...both Bilbo & Frodo...find it difficult to make emotional connections with other people

Not so, as Theron Bugtussle pointed out. To continue the psychology theme, Bilbo and Frodo are introverts*: they make a few, very deep relationships, rather than many, shallow ones.

(please don't take this to mean that I think extroverts are shallow, or always have shallow relationships - I know that into/extro debates and misunderstandings can flare up, and no-one wants that.)

Frodo and Bilbo being introverted makes sense, since JRRT was an introvert. In fact, are any of his main characters particularly extroverted?

*I'm using the term in the Myers-Briggs sense
