Well analyzed. Sleep is such a powerful factor.
The neediness you mentioned, do you know where it comes from? The source?
It would fit the idea that this need, where ever it comes from, can't ever be filled. And therefore one is looking for a replacement, 'to fill the emptyness'. If that would be the case there's work to do and a very good chance to overcome the problem.
Counting days is one thing, strict and rational. Also or even more important is looking into yourself. The underlying moods and emotions that aren't easy to find out about.
