God is the best source of comfort you will find. He knows you better than anyone else does, and he is full of understanding for every situation. Some days your heart may be filled with grief, some may hold a flicker of hope, and on others you might ache with desperate need. Lay your heart at the Father's feet and wait for his compassionate response. You can trust him completely.
It is important in your process of grief to recognize your depth of loss and express it in whatever way you can in the moment. Let God be your strength as you cry out to him. He is listening to every word you say, and he longs to reach out and draw you in close.
