my sister has studied abroad a lot. 2 semesters in france, 2 in germany......and her 1st trip to germany was her 3rd abroad trip, and she still got major homesick and culture shock. she noticed herself washing her hands an unreal amount of times in one day, and then she realized what was going on.
take some more tours, go out,
remember how excited you were about going in the first place, and focus on that. i would kill to be in your shoes right now....i know it's hard to be away from those you love (i've moved 4 times in my life, it's hard for a while)...but you won't be over there forever, and you don't wanna have any regrets when you get back to the states.
just ease yourself into a fun daily routine of seeing the sights and meeting new ppl. my sister ended up rooming with a girl she met on the bus in germany for her 2nd semester in germany. the time of her life!
also what might help (although it is super dorky, but oh well)....get to a computer lab with a scanner....scan some pictures, make a website. it's a good way to stay connected to home b/c ppl can see what all you are doing and leave you messages in your guest book. take a look at
my sister's site from her last semester in germany. there is another link to her first semester there, as well as her own homepage. i think that helped her get her mind on both germany and home....it created a fun balance for her. just check it out. it's a good connector btwn the two worlds.
good luck!! have fun! let us know how it's all going!
