Stumbling Blocks

I'm now experiencing my first hurdle. Over the past two days I've developed some sort of stomach bug that has left me extremely exhausted. It's really difficult to describe a sickness in a different language. I've managed to say "stomach ache", but that's not the only symptom I'm experiencing. My host mom and sister think I'm just really sad because I miss my familiy, which I do, but I'm also just sick. I really hope I get over whatever this is soon, because I have to admit it sucks being away from home and sick. Oh well, it can't all be fun and games, right?
