Sorry to hear of the situation. By a trauma attack do you mean a Panic Attack? What are his symptoms?
Ok, that sounds like he is very angry rather than having a Panic Attack. It is impossible to know of potential suicide risk without knowing him but if you feel concerned about his safety you should call Lifeline on 131114 as they offer specialist crisis assistance and will be the best place for you to get assistance & advice right now.
Good luck, let me know if you have further questions.
