You wake up, naked on a reedbed, you're on a swamp and it seems to be about 9am

You don't remember anything, just that you seem to have gotten into a fight recently, what sits in front of you, is a dark forest, and behind you, a mountain that goes up until over the forest, you sit on a reed bed that is in the centre of a small stream of cold, moving water; what do you choose to do?
