I think by writing your own story or just writing down your emotions about your life, it puts you in the role as an OBSERVER. A certain detachment comes as you look at your written words and feel their impact from a distance. A more rational outlook is possible as you consider yourself as the main character in your life's story. There are so many possibilities for reacting to any situations. As my widowed maternal grandmother always commented. if life gives you lemons make lemonade. Don't just stand there and complain...do something positive.
You can learn and grow from any situation, be it unfaithfulness of a companion, rebellion of a teenager or just everyday pressures we put on ourselves to be perfect. Life is an educational journey. As we interact with others, we learn so much about human nature and behavior. We learn more about ourselves and how we react and adjust to trials, temptations, and stumbling blocks that come in our way. For those who can draw on the strength of prayer, there is comforting influence that comes that can guide you in new paths and opportunities for happiness ahead. Never give up, never give up, never give up, said Churchill during WWII. You have not given up, if you keep trying to live each day despite the setbacks.
Then there are loving friends and family members who also have their own trials who will listen with understanding and care for us. We can extend that same acceptance and compassion to them as we each stumble along learning as we go. Hand in hand we journey together.
