Wondering how others deal with communication when they struggle to process information?

Been having problems recently with 'some' health care professionals; is not necessarily intentional and I don't blame them for it... it just feels like half the time we are not talking about the same thing... like it's down two parallel paths rather than the same one... has been leading to frustration on both sides and I've been beating myself up due to what I see as my inability to respond down their line of inquiry rather than going off on some tangent (to them) that I think is what they are getting at.

Not sure if any of this makes sense?

I get very worried with what I say (never knowingly rude) and when I get things wrong... is like the world has collapsed.
