My brother has called and is threatening to take his life. We'd lost our father to suicide. I have lost two brothers to alcohol-related events. This is the only brother I have left. He does this when he becomes stressed. Talked with him a long time. He knows I am available if he needs me; yet, this triggers me so much. I HATE IT when he does this; it's his "go to" behavior when stressed. My adrenaline surges/rushes. I shake.
