Someone please help.  I'm so scared.  Last year on May 4, a girl at my school shot herself.  I knew her pretty well.  She did it on school grounds so it was very hard on the school.  The anniversary is this Sunday.  One of her friends told someone he wanted to kill himself on the anniversary.  It got around and one of my friends heard.  He got my brother to go with him to the principal and tell.  Now the kid knows that someone snitched on him.  We have "Blessing Day"  in Blessing(one of the towns kids at our school come from).  The whole band (including my brother, me, the guy who "snitched", and the one who says he'll kill himself, are all marching in the parade on that day.  This kid hasn't been right since his friend shot herself & I'm scared of what he might do.  I'm losing sleep over it.  Please comment on this.  I need support, advice, encouragement, or anything
