I may have the opportunity to work in Germany for a few years. This terrifies me for a number of reasons.
Rational fear:
My parents are older (in their 70s). My mother is constantly and persistently attending chemo treatments so her cancer doesn't return.
Irrational fear:
I'm leaving everything that I am comfortable with.
I know change is good, and my initial fear is of change in general, but I'm not so young anymore, and enjoy familiarity.
On the other hand, I have always wanted to see Europe, but was never keen on temporary places to stay and feeling stranded away from home. This opportunity would give me "home" away from home. I am excited, but I also worry.
