Rome..

I still remember when I was a younger man living in Rome. It was in the latest '90ss and I was for the first time out of the home of my parents. [We usually say something like: "it was my first time living away from home," where the word "home" implies that it is your parents' home.) Some days ago [A few days ago? Or you can say: Recently...] I went to Rome again and looking back to when I first lived there, [it's not clear if you're looking back to your recent visit, or the '90s] I think it is has totally changed. Actually I do not know whether who has changed it is me or the city that has changed. Everything seemed to me sadder, almost somber. I think the wellness, happiness, and la joie de vivre that you could see down there [at that time] [Again, although I know what you mean, it's semmantically unclear. You can say "in earlier days" or "in the '90s."], had now they are [Because you are already using past tense to discuss your recent visit, you must now use past perfect tense.] completely disappeared. Some days after [I visited Rome a new] [Anew? Anyway, it sounds more natural to say, "after my last visit," or "after I visited the city recently," etc.] I read on a A newspaper article confirmed my idea impressions ["Idea" is not technically incorrect; however, it has the connotation of some way to do or explain something - like an idea for a project, or some ideas on WHY the city felt sad.] and my sadness: they want to melt [dissolve?], to break off the City Counsel because there [they?] are a bunch of criminals turning around and making politic decisions. Politicians with luxury-nomadic-mafia [Not sure what you mean here. It sounds like a descriptive adjective that needs a noun]. On the press you can read about Roma-Mafia-Politica-Zingari. What a shame!

--> I hope my comments are helpful. I'm sad to hear it! I visited Rome for the first time recently, but I had nothing to compare it to.
