My 12 yr old daughter is also very moody, she had an amalgam filling when she was 6, and it really affected her, although i didnt realise at the time. She changed overnight, she was once very outgoing, wanted to be a popstar and used to sing in front of people, loving caring, but now shes full of mood swings, gets migraines and loses the feelings in her legs, she gets bloated, cries alot for no reason, she says she feels lost, its very hard when theres 2 of us like it in one household. I told her about DMSA, shes not interested though, il have to persuade her.
