I was given an opportunity to start high school at thirteen, pretty uncommon in my country. Despite what my family was telling me, that I should stay where I am, I went with it. It took me almost two weeks to get all the pros and cons straight, but it was my most adult decision pretty much up to this point in life.
It was hard. To be honest, it is still hard. People often assume that such a small difference in age should not affect anyone or go to the other end of the spectrum; assume that this is just a kid who does not know any better. Despite the fact that I was lacking a lot in cynical aspects of my decision back then, I would still do it the same if I was given some time travel way to do it all again.
Another aspect is the fact that I am pretty much financially independent and my eighteenth birthday is about two months from now. I get my scholarship, my parents still send me some money but I have never gone above my own 'earnings'. It's a bit of a buffer, but I would consider it as my failing if I were to ever use their resources. That makes my expenses very tight, but I don't mind it. I'm on my own due to two or three decisions that resulted from the first one. It's "unfair" in the way that I can count on them backing me up (and considering my expenses vs what they send me, I could probably live for next three semesters just on that), but even in such case; Some of the students I'm attending classes with call me kid despite having their parents cash in their wallets and eating food that they did not make themselves. It's hard, but I do consider my current state as both lucky and one that I can call a point of pride.
I hope that you will get kick-ass foster family soon :D. Keep your chin up and think of Hubski as… Delad glädje är dubbel glädje och delad sorg är halv sorg ;).
