Mossy Forest Escape

I had not entered this forest alone but somehow I got separated from the other people of the group and now I am all alone. I have screamed enough to find out if the group is somewhere near but there is no response from them and so I am forced to believe that they have already left the forest. Is there any other choice for me except to explore the different areas of the forest in order to find a way to escape? I have just picked up some notes and I am trying to do what those notes read. Perhaps, I am doing what I do need to do.
