Losing a family member

This morning my grandpa passed away in his sleep. In the past year and a half I have lost 3 dear family members and I am so depressed at this point. When I was pregnant with my 15 month old daughter I lost my aunt. And then about 6 months later my husbands great grandma passed. And now my grandpa passed. I just get overstressed and depressed when it happens. I'm just asking for nice words and prayers to help me get through this!
