Hi K9 -
I had exactly this same thing happen last week. My pARNP wrote an appeal letter to my insurance for long term disability. Last week I got a call from them saying that my LTD had been approved.
So yeah - it was this huge relief. I won't have to go back to a work situation that I just can't handle right now. I'd have to function at a very high level for the work I do - it wouldn't have been a good thing for either me or the co. I work for.
But there was also this real sense of loss. And yes - it made me sad.
I think you are a positive person too. I mostly don't dwell on all the things I used to do in my "previous life" when I was very active. Instead I am thankful for what I can do now - like last Sat. I went to a movie with my wife, we spent an hour walking around the duck pond by the theater, and then had dinner. It was really fun.
But then things happen that bring our losses back into focus - and we end up with a feeling of loss - and feel sad.
Anyways, your post makes perfect sense to me.
