DS1 has just lost it big time, screaming, throwing things, etc etc. I calmed him down and got him to write what is wrong. The kids at school have been bullying him again 
. DH and I were in school last week and gave him a list of who has been bullying my son and what he has had to put up with. The deputy head said he was on it and to give him until half term.
Had a nice afternoon, friends round, ds sent to bed for being rude, got up once I came home, not sure what happened but then it all kicked off. He has thrown everything around his room. Turns out they have been bullying him again. He didn't tell anyone as he said there was no point as nothing is done and he wants to die 

.
I have told him I am going into school tomorrow and I will sort this but I don't know what to do. I can't have him suffer like this anymore.
