Is it normal to feel this suicidal about this?

Help me..Today, my old friend Josh (and old boyfriend) forced me to go to conflict mediation,( a group of teens without any diploma trying to help other teens "solve problems") because apparently I was haring him a lot..I was not haring him at all..He ually hared me about a week ago, touching me..everywhere, despite me telling him to stop. So I told my mother, and she told his father, who then grounded Josh. Josh enraged at this and was torturing me at school, throwing rocks at me as I ran, telling everyone my secrets. I told the conflict mediator that he ually hared me, he denied it..and they believed him, because they are his friends, they are on his side..After that, to no avail, I was fighting back tears..Now, if I ever say anything "mean" to him online, or at school. I will be given severe consequences. I'm suicidal and homicidal now..I want him punished severely for the ual harrasment..What do I do? Is it normal to feel this way?
