All you need to do is go in reverse, using what is called a back bearing, and follow your steps back out. Since a circle has 360 degrees, in order to find a back bearing, you need to adjust your bearing by half of that, which is 180 degrees. If your bearing is less than 180, then add the 180; if it's more than 180, then subtract 180. If it is 180, then either way will bring you back to 360 (or 0 if you prefer). So in the 87 degree example, you would add 180 and get a back bearing of 267 degrees. In your notes, also mark any landmarks you come across, like a huge anthill, or uprooted tree. That way you can remember them on your way back and it will boost confidence that you're okay. Also has the effect of a double check of your route.
