Russian landscape

In a single day I felt the Day itself and the Night, in between only a Russian Landscape in the Art lesson. I would like to know how those hormones works, Before the lesson I was feeling well, almost very happy, But back home I was feeling very down again, Only the bed gave rest to my anxiety and nervous. I also do not know if the diarrhea is the origin or consequence of the my state of mind. As who came first, the egg or chicken.

And the snow is back:)
