First time I am feeling pain in your words my dear Grandpa. This is an irreplaceable loss. My grandmother is always with you with beautiful memories that you spent with her. There is some good memories that will help you to recover from the depth of sorrow. This is the circle of time and no one can escape from it. May God give you power to bear this misery. May your happy memories give you peace.
Please accept my sincere condolences..Rip😭
