Kill the guy that kicked you with the poison lint. Then, add "Bones" to your inventory. Also, add "Note" to your inventory. Afterwards, use the bed leg to cut yourself in a non-vital area, and write an S.O.S. note on the note (in blood). Then, use the blanket to stop the bleeding, and use the bones as a lure to attract an animal that you may use to attach the note to, and hope for a rescue.
