One can feel overwhelmed and even fearful of their own grief. The best way to move through it is to allow it and know that it is a process. In the leaning into grief without resistance we honor ourselves and begin to heal.
There is no one who does not experience sorrow and you will get to the other side as did others before you. Often times the one left behind in devastation finds comfort in reaching out to those nearby and caring for loved ones.
It is important to treat one's self as though a gentle, innocent child. How would you comfort a child? Treat your sweet self the same.
