Janis you are so right losing a golden is often harder than losing a skin family member. Goldens offer us unconditional love day and night. They teach us how to love purely and so we love deeply in return. They are the first thing we see in the morning and the last thing we see at night. You have every right to feel your loss because is is a significant one.
We must have faith that Nash has finally earned his reward time in heaven for the hard work is done on earth and accept that his angelic soul was only borrowed for a short while. This also means that you will see each other again on the other side until then he will be cheering you from the sidelines and eagerly awaiting your arrival. When your souls reunite it will be an incredibly powerful moment. Faith is what will keep him alive in your heart.
There is a saying that we must turn our faces towards the sun because shadows carry too much sorrow. May the sun shine brightly for you today and remind you of all of the blessings that you still have including a wonderful and loyal guide to protect you as he always has even though he may be gone from your sight. Our thoughts and prayers are with you. Good luck with your continued healing.
