Sometimes we are aggressive without knowing it and the people that suffer are our children, family and spouses who cannot handle it. They do try to understand but we have to realise that the behaviour that drugs and alcohol produce is of our own doing and those around us that wish for peace pray for you to come back to earth. So for those who have stopped a habit... congratulations!!!!!!!! that is a huge step and those who are in recovery and feel that they have no idea why they are having outbursts or aggressive behaviour, this is normal for your brain to begin to find balance somewhere along the line and it takes time but be patient and allow your family in so that they can understand why you are doing what you are doing.
