How plagerism has effected me!!!!

My junior year of high school we had the opportunity to write something, whether it be a poem, story, or just something written down about things that have effected us. I had worked on a poem for 3 months, then we were told that we could write something and it could be published. I turned in my poem to the English teacher in charge of the activity, which was my English teacher. Well that teacher left it out in the open for any and everyone to look at it. A few days later my teacher had called me to her desk and asked me if I had taken the poem off her desk, and at the moment I knew that someone had taken it. I found out that my poem was publish, but with someone elses name on it. I will never forget that day.
