I am Dutch but moved to England (for love) 16 years ago and I have never regretted it. Do it while you can, else you will just live with the regret. It is such a life experience moving countries, there is no way to describe it. The magical feeling that you have in the beginning does disappear a little over the years, but it never leaves completely. The memories you create are just so amazing that you will never lose the magical feeling entirely.
Just. Do. It.
German jokes are the wurst.
