My son's first church camp

I sent my son off to church camp yesterday. I was a little worried about how he would do. He has autism and I know it is very chaotic there and not alot of heads up on what they do for the day. I got a call from the camp last night asking questions about him. I'm worried that by tonight I will get a call from them telling me I need to come get him. I just want him to have fun and to learn more about the Lord. I was hoping he was old enough to be able to handle this week, but maybe it's just not a good idea for someone with his condition. I know that if he does ok, and stays the week, I will try to do more next year to get him a "buddy" that will go with him everywhere (basically like a para). I know as kids get older it's harder for the parents to let go and let them do their own thing and live their own lives, but when it's a child with a disorder or disability, I think it's alot harder. I worry if they are giving him his meds, I worry how he's handling all the noise and singing. I worry that he will get scared at night and no one will be there to comfort him. The only thing that gives me peace is the fact that there are several adults and youth there helping that he knows and that know him. Several of them told me they would watch out for him. That made me feel a little better. I have found myself doing little short prayers for him since dropping him off yesterday. Is it bad that I'm thinking about him so much? Am I a worry wart, or is this normal......*sigh*
