I would mention that to her. Not because she is likely to say..."hey OK lets set up an IM connection for next week." Of course, she might... but probably not. She might be able to use this information in some way to facilitate your verbal communication or at the very least explain to you why she believes it is import to get stuff out verbally.

For me... the fact that I can now write certain things, draw certain things, but still get REALLY triggered when I have to listen to them read aloud or even worse SAY THEM MYSELF out loud.... tells me...something. At the very least it suggests that telling and listening are different in some way (at least in my head). I still have a few wires crossed or something. Since most interpersonal communication occurs via face-to-face oral exchanges... my hypersensitivity is likely still inhibiting me.
