Kimber,
Alone is a feeling...real, poignant and powerful.
Reality is that Don is still with you. His spirit rests in your heart and is with you daily, just like Jesus.
You are not alone. You are among those who care and feel your pain, but grief is a process and as in any process, there must be a beginning, a middle, and thankfully, an end to the torment and agony of pain.
You will always love and miss Don, but the pain will subside and the Sun will continue to rise.
Keep the Son in your eyes till then!
