As I know, in Don't Starve vanilla, there's a giant cave with 3 entrances (sinkholes), maybe you could open your map underground and see how far or where was the last place you stayed before died. The cave don't change each time, maybe you just entered from another place. Cave is a really hard place in my opinion, so be careful. One more thing, get some grass, twigs and berries, craft torches and try to retrieve your stuffs.
