A September day.

It was early; everything was quiet. There was no sound at all and the sun wasn`t hadn't yet risen yet. I was preparing breakfast, like every morning, but something was different at this time. I get became paralized for a few seconds thinking on of what the hell was wrong! And I 'd said to my self, "it must be something important". and I had contiuned continued thinking about it while I was finishing my breakfast, brushing my teeth and dressing myself. And once i'd I got in the car...Oh my Good, that thinking becomed became clear. It was Sunday and I was sitting in that car prepared to go to work at 6:00 AM on a lovely day off. I'd I felt really stupid and I went back home and went straight to bed.

The positioning of your punctuation is not correct. The space must be placed after the puctuation and not after.

The tense is a little confused. The simple past seems more appropriate than the past perfect. The past perfect places something in time before something else. This doesn't seem to be the case in your story.

It was early, everything was quiet, no sound at all, the sun hadn't risen yet. I was preparing breakfast like every morning, but something was different this time. I stopped for a few seconds thinking about what was wrong! And I said to myself "must be something important ". I continued wondering what it was while I was finishing my breakfast, brushing my teeth and getting dressed. Once I'd got into the car I suddenly realized: ...Oh my God, it was Sunday and I was sitting in that car prepared to go to work at 6:00 am on a lovely Sunday morning. I felt really stupid and went back home and straight back to bed.
