Any tips on how to play this game?

Was going in to this game expecting dark souls, but its alot harder than I thought?

Already payed the blood debt, spoke to the 2 npc who go off on there journeys,

After that I just been getting my self handed too!! At 1 point i got locked in a bandit camp and had too escape.

The map is very awkward, as it doesn't show you where your going? also placing a waypoint on the map doesn't show anything. So whats the point of it?

Where do you get water and food? Where to get best armor and wepaons? Like what the hell do I do lol.
