She's just completely withdrawn

[keannu]

I've heard some cases of "withdrawn" and some of them were translated as "isolated" and some "shy", it seems to mean "you are trying to hide yourself and not to talk". What is the exact meaning?

g.w2-4
Mel- She ok?
Jim- Physically, she's fine. She's just completely withdrawn. She won't talk.
Mel- Sounds like somebody else I know.

The exact meaning is known only to the speakers, who know the full context of situation.

I believe we know enough to be quite sure that "withdrawn" means not inclined to communicate here.
