I am looking for some advice - For the last few nights my DS (ASD 9) has had difficulty getting to sleep at night. He gets himself worked up into a state as he says he hears voices in his head shouting/laughing and they prevent him from getting to sleep. He is cuurently in MS school but has always struggled both academically and socially. Is this an anxiety issue and has anyone out there had experience of this? Am rather concerned to say the least. Thanks
