I am posting this on two boards (sn and behaviour) as I have no idea where I should be posting.
My question is, where do I go for help with DS outside the school system ?
Background.
DS is 6 yo. He is very quirky. Doesn't sleep much. Often ignores us when we call him. Highly anxious especially about school and struggles socially.
He has had a stomach ache since September the doctor says it does not have a physical cause..All the same it worries me.
I have really struggled to walk him to school over the last few years. He reacts anywhere from verbal complaints, refusing to walk down to threatening to throw himself in the road under a car and kicking and hitting me. He hates school.
He claims to have no friends at school and is never chosen to have a partner. He also claims he has 30 best friends, as the teachers told him he had.
He will say anything to stop the questions. He changes his opinion at the drop of a hat, so trying to get an honest opinion off him is very difficult. His teacher last year agreed this was the case. He masks all the time at school, as he is frightened the teachers will shout or hit him !
He never gets play dates or party invites, outside a couple of my friends who gave children around his age.
He now plays with a child with SN who often hits him. DS told me the name of the game they play but couldn't explain how it was played.
School say he has loads of friends and is very affectionate (one of my concerns, he would go off with any stranger)
School say they see no problems. They don't see him spinning across the playground, bolting ahead paying no heed to the traffic on the way to and from school.
He is so anxious that he won't sleep in his own room and insists on sleeping in his sisters bedroom.
He won't be upstairs or downstairs on his own...he is too frightened. We have a rota for people to go with him to the toilet..else he will have an accident rather than go on his own. 
As he is also frightened when everyone else is asleep. So when he gets up at 3, 4 or 5am he will wake me and/or his 4yo sister up....We are on our knees with tiredness.
He struggles socially. Doesn't get social rules or understand games rules unless they are carefully explained and then he follows the rules rigidity and gets very upset if anyone breaks one.
He does not get irony or sarcasm and takes everything literally. Ask him to pick up the plates...he will do but he will not pick up bowls or cups as they are not plates.
He hates change and gets upset if things are sprung on him. So we use a visual timetable.
He tries his best to socialise but often stands too close, often shouts (volume wise) and hugs tightly when children don't want to be hugged.
Children try to interact with him but don't get him and sometimes he can react badly which doesn't help.
His only hobby is an obession with Minecraft and to a lesser degree Skylanders and he would spend all day on a computer if I let him.

Professionals.
Audiologist said he has normal hearing range. Plus sensitive to loud noises. Concerns about social interactions.
Comm Paed said Issues with Minor and Gross Motor skills..referred to OT. Concerns about social communication interactions referred to a special panel to discuss.
Outreach assessment at school. He makes many attempts to socialise therefore fine. I disagree, he can't socialise properly...failing to socialise shouldn't be a pass but it is. So panel via Comm Paed will give no help because of this assessment.
SALT says social communucation difficulties...particularly due to rule understanding and social rules. Referring him for social classes with a 6 month waiting list.
Education Psychologist listed issues I was concerned about. Ignoring other children and being rule bound. Not listening to teacher in class and not understanding rules of the game he was playing and then told me it was all normal for 6yo boys.
She started off by telling me how fine he looked at school and how many friends the teacher told her DS has and finished by telling me how a child had tried to interact with DS, who had turned around and screamed at them and said no wonder he has no friends if that is the way he behaves ! She also agreed that he says whatever you want to hear and will change his answer in a second. I think this is masking difficulties, she said it is normal.
Behaviourist sent to my house by headmaster due to DS sucide threats, as the problems were clearly at home 
Behaviourist admitted the school did not believe me and DS looked fine at school. She agreed that there was no issues in our home and we are good parents.
I also completed an Triple P parenting course on my own bat...as I wanted to check it wasn't me...it taught me nothing I don't already do. Family Lives who offered this course do not offer anything further..I did ask.
Senco is a nice lady but clear she sees nothing in DS. She has emailed other professionals telling them, there is nothing wrong with DS and the mother (me) wants something wrong with her child DS has his own sticker charts for behaviour, IEP 's and I hear how often he loses golden time....Yet he is just a normal boy.

What can I do ? I just want him to be happy and stop worrying about being ill, being on his own, thoughts about me dying and faceless monsters.
Ignoring school who will never help.
...what can I do at home to help him ?
ps. Be kind as I am a bit oversensitive as our 2yo has failed her 2 year check for the same issues social interaction and language problems...her hearing is fine and we are going through the system with her too.
