i'm sorry you're sick. unfortunately, if you go back to germany (i'm not sure what your travelling schedule is), it won't be much better there. i know they're really into homeopathic shit and it can be hard to find a lot of over-the-counter medicines there, even mild painkillers. i'm not talking serious shit, i'm just talking stuff you'd take for a headache.
i guess nothing should surprise me since when i lived in nz, i was amazed to discover neosporin wasn't sold there (it's an antibacterial ointment or cream, depending on your preference). i don't take antibiotics for everything and don't put neosporin on every cut, but around this time last year i fell and got a huge scrape on my knee. i was about to go camping and we'd already left our apartment so i couldn't really clean up properly, but luckily my bf always keeps a first aid kit in his car, so i could bandage it and put some neosporin on it. i still have a huge scar, just from tripping on some uneven pavement. ugh.
