My grandma been only one there for me forever and I am taking care of her and she is on Hospice how I handle her death when I'll have no one to help me with the grieving process?

I am so sorry to hear about your grandmother, it's always sad to see someone who we love so much suffer as their health starts to go downhill. Two years ago we watched my grandmother as her health declined until she passed, it was definitely a hard thing to experience. But what helped my family get through the grieving process was meditating on the hope we have in The Bible. On scripture I find comforting is found at Job 14:14,15 where it says, "If a man dies, can he live again? I will wait all the days of my compulsory service until my relief comes. You will call, and I will answer you. You will long for the work of your hands." This scripture is saying that when our loved ones pass away, not only do we feel the loss, but God feels the pain we feel as well. This scripture in fact says that he longs of the works of his hands, so he misses his creation and can't wait for the day where he can bring them back to life. There are more scriptures like this found in the Bible, that can bring us comfort like that.
