After the death of my father at home, how to reply to the concerned messages sent by others?

I can reply like this: thank you for your concern. Although my father's death hit me hard and made me very sad and painful, I feel much better with your comfort, because although I lost my father's love, I feel very gratified and satisfied that you care for me and take care of me like a relative. I will definitely come out of my grief and live up to your hopes.
