What  happened to me  today.

As usual, today I got up at 6:15am and  went to the gym. My workout included; warming up, biceps, chest, abdominal exercises and stretching in a intense way. Afterwards,  I shaved and had a  shower.

Then I came back home in order to tidy up and have breakfast. I  arrived at the office at 8:30am, working until 17:30pm, with an hour's break for lunch. Later, I  attended my French class from 18:00 to 19:15.

  Also I also attended to my oral English class and finally I came  home.

I  had supper and now I am writing about my stressful day. I would be pleased if somebody corrected my essay,  but I'd rather to speak with somebody by skype instead  of writing. Thanks

Hi, I changed some of your verb forms, for example, "have arrived" generally means that you have arrived sometime before in the past.  Since these things happened once, today, you would use the simple past tense, such as "I went, I came"
