Help urgently needed to finish an international move gone awry!

My dear friend is moving to Finland from Estonia to start a PhD, and I flew out after a conference to help. Money was already very tight for me, but then we’ve both had major complications. Now there’s no money, and we may be stranded. We’re sleep deprived and desperate.

My friend has worked so hard for this opportunity, and now they’re looking at having no money to return our rental van (need ferry tickets and petrol) or buy food for the next few weeks. I have to fly back home on Wednesday, and I’m not sure how I can even get to the airport. It’s an impossible situation that could be solved with a fairly small amount of money that we just don’t have. Thanks for any help you can give!
