many ModPacks use a minimap that will automatically create a waypoint to your most recent death point. I would suggest looking there.
Staff will not help you retrieve your grave if that is what you are asking. As Broklyn_Datroll stated, many mini-maps track death points. If you don't have a mini-map, you might be out of luck.
The problem is, I have disabled the dead points of my mini-map, it is possible to see the dead points in the server console
