How Do You Cope With the Loss of a Loved One?

My grandmother just passed away, and i am completely torn. She was the only grandparent i had and was an angel on earth. This year has really taken its toll on my mental health,. And losing my grandmother was the last straw. I am trying so hard to inmy purpose every day and to have positivity but there has been so much bad news it's hard to even get up in the morning.
