This could be seen as a crisis situation by the insurance company if reported that your beloved unc died. That could certainly be a justified visit.

So sorry about your uncle.

But then again... if he feels you need to feel the pain... well if the pain is not about your uncle.. that could get in the way of therapeutic progress. I am sorry. I do not know the answers but think if you are missing next week... why not go this week. Seems worthwhile to me.
