I know this girl like the back of my hand. I saw her behave like this many times, in regard to changes I needed to make as well. I know this may sound off the wall to some, some may completely understand what I'm talking about.
At the time this was happening, I brought it up in one of our Hospice meetings. I then understood it to be a stage of the entire process. I thought it was going to linger and continue to worsen as time went on.
On a subconscious level at first, I began to mirror some of Aviana's actions. I realized I was actually detaching a little from her. It made me sad, but I couldn't help it. I suppose it was a defense mechanism or something of the sort?
An interesting thing happened though. After Aviana showed everyone her needs, and they were validated...the phase was instantly over and thankfully never returned. Once again, I mirrored Aviana and was right back by her side. It was an interesting, and necessary stage - I guess for both of us.
