Im glad u aint my kid
But that being said. You are 18, and yes it will be nice to get going on college and I think your dad should let you go to college so you can get that over with posthaste. Maybe there are other reasons. Maybe you can take this as a golden opportunity to learn something new about life in general by living in Taiwan. A whole new universe from the one you know.
But yeah it sucks. I think most anyone in your situation would feel much the same.
Ride it out a bit. Go to the taiwan military (its softer then the US or Canadian one I hear)>
TAke this opportunity to get to know your dad better too as a person. Lots to learn and to enjoy too, if you give it the right attitude.
