I have a question??

My son is 7 with autism & adhd & he’s also non verbal…he woke up at 7pm I told him to turn the light on and he did then I ask him to come here and he was acting scared as if I would hit him and when I would ask for a high five or try to give him a hug he act like it hurt or he was afraid and I’m confused cause he had OT earlier that day and was happy jumping around before and afterwards.

This never happened before so I just wanted to know what do I do. Right now he’s eating his snack and he’s happy but when I ask for a high five again he just points his finger at my hand as if he doesn’t like the feeling I don’t know, I’m just trying to figure it out cause it’s something new and he’s not crying or screaming. It’s 837pm now…how long does this last? Advice please?
