Anger issues in 16yr old boy

Hi. I’ve joined to get some advice about my son who’s 16. 
he was diagnosed when he was 2 and as a family I think we have coped quiet well up till a few years ago. But then puberty kicked in and my sweet boy is now an angry frustrated man. 
he doesn’t understand peoples intentions when they are talking to him so instantly thinks they are feeling the way he is. Which 9/10 is anger. So everything is a battle. I understand teenage boys are hard to deal with anyway but he goes from laughing to smashing his room up to crying saying he doesn’t want to be here anymore within one meltdown. 
anyone have older children that have been thought this. I’ve tried every tactic to help him but I’m still the villain and I can’t do anything right 

so from one desperate mum who is crying out for some help, I do appreciate any suggestions on how I can help him 

thank you Blush
