I don't know that this has much to do with aging. I am 41 and I have lived through the my brother's violent murder, the loss of close cousins (nearly siblings) to a car accident, a workplace accident and domestic violence, illnesses that took the lives of friends, and a years-long sickness that took my mother this year. I worry about how to care for my dad every day. I have chronic health issues and struggle with daily pain.
Life is really hard sometimes. I understand that with the addition of years in my life there will be more loss. There will be more pain - both physical and emotional, more doctors, more therapies and medications.
Life can be sad, but we don't have to let it overwhelm us. We don't have to let the difficulties in our lives cause us to hate this existence.
I am proud of my age and my aging. My face is starting to show lines when I smile. My hair is graying. My waist is getting thicker. My eyes fail me most days when I try to read. I choose to believe that these are gifts that I've earned for making it this far.
