AITA for freaking out because my parents bought me a one-way ticket to Korea?

I (16F) am a first generation American with extremely strict Korean parents who have a "no-nonsense/no questions allowed" approach to life. Recently, they announced they are sending me alone to Korea for the summer to visit cousins. I found out that it’s a one-way ticket and they won’t tell me when I’m coming back. My parents have been whispering all morning, and my mom came out humming and looking "very happy". Which just adds to my fear. My best friend thinks I’m freaking out prematurely, but they also just bought a suitcase that could fit me and everything we own in the bag. I even called the American consulate to see if I can get out of this trip, but since I'm a minor, I'm stuck.

AITA for suspecting my parents are shipping me off forever?
