I'm stuck running around in the wilderness barely able to see anything. I know you can sleep in a bed but there isn't any around?
Unfortunately there is no waiting like there is in TES games.However did you think about using a torch? They are easy to find and you usually have bunch of them with you if you don't sell them.
Other than that you can stay in "safe" spot and wait until game time changes.
You could usually fast travel few times between 2 distant locations but you need map and 2 locations discovered for that,and I don't think this will help your situation much since you are in middle of jungle.This method is best in case you can't find any beds.
