AITA for not moving to another country with my parents after I turned 18

A couple of months ago I (F18) turned eighteen and finished my school here in Germany. Basically not even a couple of weeks after my parents (F44/M48) revealed to me that they want to move to Japan and I should come with them. Little backstory, my dad met my mother in his 20s in Japan on a business trip (she's Japanese) and a couple years later, he met her randomly again on vacation in the US. Since then they have been together.

I told my parents that I do not want to move to Japan because it would basically be a restart to my life and in this important time period in my life where the next big steps are happening, I will need them, my friends and a familiar place. That started a huge fight and they started to complain that they did everything for me all my life and stayed in Germany because of me and that I’m being ungrateful for making it such a trouble to pursue their plans. Also they told me, if I don’t go with them, they will be super disappointed and will not support me if I stay in Germany.

I told them I need a couple of days to think about it. Now I don’t know what to do and I’m scared to stay alone here because I really don’t want to go, but I do not want to lose them either. Am I really the problem here?
