ITH - It's great that you are thinking ahead of things that you want to do for yourself once you return home but you need to some things for yourself now too!!! And oh boy do I know how hard it is to do when you are broke as I am too!!! LoL
I know you are in Poland but is there someplace there you can go hiking, or a nice walk. Do they ever have any festivals or fairs where you can just walk around for a bit. That's why I enjoy my little arts and craft fairs so much..they are usually free admission and I enjoy just walking around looking at all the stuff even if I can't purchase anything.
