With having lived there and if you are fluent in German, unless you really want/need to study abroad at this point for a refresher (see friends/family/travel, etc.), most schools offer the opportunity for life experience accreditation (called different things at different schools) to test out of it.
I travelled extensively in middle school and high school, doing a type of study abroad during the summers in high school. Being an international relations/language major at one point and study abroad being required as well, I was able to do testing in college so I did not have to waste time, yet another semester for a credit I already had the experience. There is usually a fee but it is much less than that of the full credit for that class ($150-400 for the test at the schools that have been too) vs going abroad with full credit hour fees and might save you some time getting you to graduation sooner.
Perhaps this is an option for you to look into. I love to travel but getting done with school at times is more critical. Taking the time for abroad at that juncture for me was not an option as I needed to graduate sooner than later.
Viel Glueck!
