stuck in tokyo japan

I came to Japan on a one way trip alone for 2 weeks, thinking I have everything under control. I ended up losing my bag containing cell phone and other needed stuff for my travel, now I'm looking for a good hall way or a warm place to start calling home before my last three days in this hotel I'm staying in. so I'm hoping and praying this will help me though my way. I've been eating noodles by its self, sometimes I get lucky if theirs left over snacks at the park. please help me get back home and get some food to keep me going. god bless you all..
