Is this normal? Moved abroad but I can’t understand my own feelings…

Hey guys, I moved abroad (Germany) in October and honestly I can’t even understand my own nature right now. Sometimes everything feels fine, and sometimes I suddenly feel empty or weird. I feel like crying sometimes… and sometimes I don’t feel anything at all. My mood is all over the place and I don’t even know why. Is this normal? Has anyone else felt like this when they moved abroad for the first time? How do you deal with this phase? I’m really confused.
