Adjusting to a change or loss creates a group of symptoms, such as stress, feeling sad or hopeless, and physical symptoms that can occur after you go through a stressful life event. The symptoms occur because you are having a hard time coping.
Even with its elements of sorrow, loss, and regret, remembrance means that love for those we've lost has no final act. Through remembrance, we continue to love. Remembrance and the love it perpetuates can move us beyond grief as we remember the loss as a whole.
It is my belief that personal attachments and connections are the roots of much of our behaviors.
