Guys & recklessness

I mean its probably normal for him to feel sad and everything about me moving. BC I just recently move to Texas from Alabama. He had a bad temper and is really clumsy. Before I left its like anything makes him mad now without me being there or texting him. He also plays football and that probably helps him with his anger but he's been so reckless getting hurt more often because of his recklessness and clumsiness. I just don't know how to support him being so far away and help him when get gets hurt or in fights.. So does anyone have any advice to give me for what to say to him about it?
