Translation of Abscheulichkeit

I have started learning only one month ago, that was during the summer holidays, I want to go to Canada for three weeks and then participate in a course. I hope that I will improve it more or less.
I met the company last autumn, because the site's traffic is getting pretty big and they invited me to a workshop. They have convinced me that I have to put their logo at the top of the page to maximize exposure and this was a big mistake.
So this is my last week here in Germany, then it's back to Italy. I'm not sure if I will return soon. But I am longing for friends and family. I will certainly return one day, that is sure.
