Some advice on how to fill social security form for autistic child

Hello everyone so i finally got the appointment for my son and thank god because i need it so bad

i dont recieve child support so this will help me take care of my son, my poor boy has barely any clothes,

only one coat , and a pair of sneakers that barely fit. he loves his crocs anyways his stuff is getting old.

I got some form and they want me to include his autism diagnosis and my boy stims not so much but

he has a hard time understanding me , he is non verbal.. i would say hes okay but he needs therapy,

i had an incident at his old daycare where he was screaming and the daycare owner said they put

something on the tv to scare him and she switched this so i involved acs because the workers were lying

and didnt want to show me the video . i immediately quit my job and iv been stuck home ever since figuring this out

so if anyone has any advice to help me with this process .. please and thank you
