Tired Tiring weekend

I had a very hard week, riddled of with meetings, deadlines, trips, and calls. I arrived very, very tired on Friday, so I fell asleep as if I were dead.

Today I woke up at 9:30am and read the news. Almost all the opinion columns were about the past  recent polling day, that which was last weekend. Every All parties say they won, but at the same time say there were was fraud in the election. I guess the next 4 years will be very difficult to for my country, at least in the parliament. Ex-President Álvaro Uribe is now a Senator, an he is oppositor of in opposition to our actual President, Juan Manuel Santos. The country starts is starting to polarise again, and the politicians starts are starting to yell instead of talk.

I think you might have meant to say that you arrived HOME very late on Friday evening? 

By opinion columns I think you might mean editorial columns. Those are the columns in the newspaper where people give their own opinions rather than just report the news. 

By oppositor I think you meant to say that his is an opponent no? ... and he is an opponent of our actual president.
