DS is 16, he has ASD and has a lot of suicidal thoughts and anxiety (he is on anti depressants and sees cahms).
I came home from work to him having a meltdown, DP had taken the laptop off of him as he was getting very frustrated with it but DP didn't know why so he told him he was taking it as it was upsetting him, he then had a meltdown, I did manage to calm him down by hugging him and we then went out for a walk which seemed to help so I thought he'd be fine.
At about 10, me and DP told him to go and brush his teeth ready for bed, he refused and this led to another meltdown but he was trying to hit his head on things, punch things, bite and scratch himself, trying to smash his things etc and he saying over and over he wants to die. We managed to stop him and he's currently laying on the floor crying, which isn't ideal I know but we know he's safe and isn't trying to hurt himself anymore and I will go and give him a cuddle in a minute. But he's a danger to himself when he's like this and he's had 2 meltdowns already today so I'm dreading if he has another 
I know some people will judge but WIBU if I take him to A&E?
