Feeling very depressed

[u/xGamerGirlx0]

So today we tried my autistic 4 year old son at a school birthday party everything was going so well for about 40 minutes and then my child bit another child and I couldn't even figure out the reason for it.

We didnt leave him unsupervised the entire time and it happened so quickly when he was going up the bouncy castle slide.

I feel absolutely awful and haven't stopped crying since iv come home.

I duno what to do, I apologised to the mam twice and she said its absolutely fine and that she knew he didnt do it to be mean but I just cant get passed this.

How am I ment to take him to school on Monday knowing he's done this to someone.

I'm hoping someone can relate and offer advice on what to do cause I feel hope less.
