How could this happen?

My friends turned everyone against me.
I dont know how this came to be.
One day everything was just fine but then the next day,
everything went all the wrong way.
People laughed and made me cry.
MY "friends" would point at me as I walked by.
At luch no one sat with me, i ate alone.
I just wanted to go back home.
I dumped my tray and went to the next class.
Everyone was starring at me so I asked for the Nurses pass.
I took all my stuff and said I didn't feel good.
I walked out of the room and pulled up my hood.
I didn't want anyone else to see me.
I went to the bathroom instead to write an apology.
But I didn't know what I did wrong.
We've been friends so long.
Why wont she be my friend?
I can't believe this friendship has come to an end...
