GOd Bless you and your child.

Look into PharmaNAC. It has been studied with respect to autism in double blind studies and showed efficacy in reducing repetitive behaviors. Was being studied for OCD behaviors. Also look into PANDAS or PANs which has OCD and autistic behavior as symptom/co diagnosis.

Any bullying issues ? if so that is a big component to self- estem and self worth.. We can talk about the Sticker lesson visual aid that I developed a few years ago for my kids if the bullying applies, Get a picture of your child, put his photo in the center of a large white poster board you can have him draw or explain specifically what it is he is not satisfied with what is the anxiety about? is it the people in a room is it movement is it noise ? put any negitive descriptions on a squares black paper.on the back side some Velcro to put on the boards like to stick it on there or use stick it notes! Do you need to throw some feelings in the garbage ? The truth is they are not helper feelings. Helper feelings are on the white board with the helper people you are in the center.... the sad/ negative feeling feel black, anxiety makes you stop, and worry and scared.. They can not stay on your white poster board for long teach him to peal them off and throw them in the garbage. or find a helper to encourage him (If you are anxious do you need a ball to squeeze do you need a back rub? do you need a warm pack or a cold pack? . You will need participation of other family members, they have there pictures and friends and GO TO helpers like teachers or so for the he feels comfortable with to ask them to help him! to add outer peramiters of the white board have them write in bright boxes with comments on that with the Velcro back on that.. all the things they love about him. show that those cover up the black ones easily. Show him the facts daily have this in a central location for him to referance. have a bag of feelings with the velcro on it an a bag of the good feelings with the velcro on the back of that...those key words could be like Confident, courageous, love able , Like able. good friend, caring brother. good listener , great artist, good at basket ball , Many children on the spectrum do better with Picture/ word association... work on building that area up. you give him internal visual tools to keep those negative thoughts in check... continue to direct him to the board, and his feeling cards that are with the Velcro. You are providing a outlet for his feelings and appropriate seeking out help when he needs it,so he wont stay stuck like a record every day ....Show him he is the one that can navigate like with a inside attitude compass.. you do have those feelings,
agnowledge that they are there.. but what do we do with them ? have him compare what is the better choice, What is the truth? the truth is you are LOVED, you are LIKEABEL you are a A CAN DO KID ! Don't let the black lables creep over and give you a sad inside..or the creepy anxiety stickers. look into your positive white poster board this is like a mental space,, Show him a visual that the black thoughts you can control and keeps them out from invading your nice positive white space. Just an idea .

Cognitive behavioral therapy can be very helpful in managing OCD. Does he currently see a psychologist? If not, that would be a good place to start. Especially if you can find one (and it shouldn't be too difficult) who specializes in cbt.

BTW my children were diagnosed with PANDS after we were exposed to toxic black mold ! - look at your home as well make sure it is dry - and all areas he sleeps have good air flow and no stinky must smell
