Adjusting to one or more significant life changes is an unavoidable, essential, and natural neurological process. It is also deeply unpleasant and difficult. When people do not understand what goes on in their brain when they are grieving/adjusting to one or more significant life changes, things can get much more complicated, and much scarier than they need to be. Most people tend to worry there is something wrong with them, or that they are going crazy. Understanding how grief/adjustment to change affects our brain, helps us worry less about what we are feeling. Instead of trying to stop the process, avoid it, or 'get in its way', we can support ourselves and others much more skilfully. When we handle grief/adjustment to change correctly, we do not just 'endure' it, we can continue to grow and develop right through it. Children and young people inevitably go through constant and dramatic changes that frighten them, and often lead to crippling anxiety. Adults need to understand grief/adjustment to change so they can support children and young people properly. The content of this book should be a part of any school curriculum, and should be available to anyone who cares for children. This short book goes right to the bare bones of what the process of grief/adjustment really is, and everyone can understand it. I kept it short, because when people are grieving/adjusting to one or several significant life changes, they often do not have the 'brain space', or concentration to read a long book. (Temporary lack of concentration is a normal 'symptom' of grief/adjustment to change). This short book has helped many people around the world to feel much less troubled and frightened during grief/adjustment to change. This book is a part of the 'Fully Human Psychotherapy Tools for Life Series'.
