Bit of background, DS is 7 (8 in Oct) just started year 3, generally he's a happy boy and there is no reason for him to have worries or anxieties.
As a toddler he was a cautious child but not overly so, had some anxieties about the dark etc but nothing out of the norm.
My cousin died in 2011 suddenly and she was quite young, he barely knew her but did ruminate over death etc for quite a while but I felt this fitted what had happened and that he/we had sorted it out.
Recently over past few months he has expressed anxieties about dying again, getting killed ( this got worse when the news coverage was shown about the Woolwich murder although he was protected from that as far as possible), burglars and 'bad people', wars, historical deaths such as hanging of pirates and execution of historical kings etc and whether these would happen now.
He has said over last few days that he does hear noises at times but not really words, he worries that these 'noises' might tell him he needs to do bad things but denies that they are telling him things like that.
On holiday there was an incident where a child threw sand at him which got in his eyes, this was dealt with but he now keeps thinking about what if someone held his eyes open and poured sand in to hurt him. He has come home today saying that he has been thinking about what would happen if he used a knife to cut the skin between his thumb and index finger, would it split, why would someone do it.
He is obviously upset by these thoughts and seems to constantly ruminate over things.
If you've got this far then thanks for reading but I don't know where to go with this from here and how to help him feel better.
Thanks in advance
