Your first step you should do if you find yourself in a survival situation is not move. The more you move away the more you are making it hard for people to find you. At this point make lots of signaling fires, using lots of wet leaves and dry wood and wait.
If you get the feeling that you will be waiting a while, then set up a few traps and try to catch a bite to eat. If you are near stream, get a woolen fleece (if you have one) drape it across as much of the stream as you can, making shure that nothing can go under (it is better for it to be lower in the water than high) and wait a night.
In the morning come back and you will hopefully have lots of small fish caught in the holes in the cotton.
