my own inner energy

I feel so strange – I can't do anything.
It seems to me, that I have spent too much of my own inner energy. I understand that I spend this energy constantly, even if I just sit in front of the monitor. But I can't restore it often. Every day I receive energy while sleeping, but it seems to me, that I receive it less, than I spend during the day.
Once I had a very good rest in Cyprus, but it was long ago, so long that I almost have forgotten everything. Certainly, I remember some small and bright impressions of beautiful sunrise. I also remember that once at night, standing on a balcony of Amathus hotel and looking at the sea, I has understood that it is alive. Such quantity of energy that I have received from swimming in this sea, probably, I did not receive never before. The truth there was unique time when I swam in a special pool with water which flew from mountains. It was very hot water. It was specially cooled off. This happened when we have left from Dubai for excursion to Oman.
