How can I make progress at my Italian?

Yesterday I had an Italian lesson. It was very easy. In spite of fact, we finished only 4 pages of the text. We learned only noun's rule. I fear that my Italian becomes bad, so I went to seek a book for my study in Kanda where everybody can buy some books in Italian. But that book store vend some difficult books for me. I must to go at Termini, because there are a book store where I can buy some easy books in Italian for foreigner, but now I live in Tokyo, I can't go to that book store. I'm sad. I want talk in Italian with my wife.
My anxiety is that I don't job. I want job, but I don't like Japanese boys and girls. Their culture isn't interesting for me. Yesterday I worked in a way near the department "Takashimaya", and I heard a song of the young girls. That song isn't good for me. I don't like it. I don't want listen the song of Japanese girls. I want listen European and American songs.
By the way do you know Roberto Vecchioni? Now I like his song "Chiamami ancora amore". I add it my karaoke list on the you tube. The lyric is very beautiful for me. I want sing this song.
And now I diet, but I don't become thin. Now I'm fat. How can I become thin?
See you
