DS is 7 and has suspect ASD (aspergers) - he is currently going through the investigation process.
Anyway, DS struggles with school massively. He struggles on a daily basis with most activities. He has quite a few panic attacks and needs to be calmed down quite often by being taken for a walk. It is always much worse when DS has been off school over the school holidays. DS gets anxious a few days running up to him going back to school and struggles to sleep due to worry and gets quite emotional when talking about it. He also gets very clingy with me and wants cuddling to sleep and likes me to be around him all of the time - which of course, I don't mind. 
DS is due to start school again after this Easter Break on Tuesday. Tonight he got very emotional, needed me to cuddle him to sleep and will spend the day/night worrying about it tomorrow. Is there anything at all that I could do to help him? I try to reassure him over and over. It doesn't help. Any advice would be hugely appreciated. Thank you!
