Did you (students) questioned going to uwc after nomination?

I think i am struggling with the huge change. I am questioning if its worth to leave my country at 16 even though i wanted to attend uwc for 2 years. I accepted the offer anyways but it feels weird. I know i want this, i know i want to go but something feels wrong and idk what it is. I know i am ready to leave… I think i am just stressed but i still wanna know, did any of you also experienced this?
