The situation is not directly resolved by the law, so it does interfere with my freedoms. It's fucking complicated. Good to mention I don't live in USA.

It basically stands on the fact that I am not economically independent yet (catch-22 a bit) - and at 13 I obviously wasn't. There is an obligation to take care of a member of the closest family living in the same place from the same income. There initially was a chance that she would be a warden of the state, but because she is mentally healthy, she had to approve, which she didn't, not even thinking about the impact on other people (she's a stupid bitch). And this was even confirmed by my father (who ridiculously left after some time, which he could because there was still underaged me unable to defend). Once the decision about homecare was taken, the only chance to defer her out would be paying for it, but the institutions are more expensive than the homecare ('cause I'm a free workforce), and that's too much for the state support my mother receives.

So my only way out of it would be making money, which I am making my way towards, but it's severely affected by the fact that my college studies (free and good in my country) were sabotaged by the lack of space and time, before I got a degree.
Plus I've lost around 99% (not a guess) of social opportunities in my teens, which makes me horribly socially inexperienced. Plus I have cystic acne, which destroyed the remaining 1% and probably will turn my possible late start of life into a nightmare.

I was probing the possibility of a lawsuit when I've hit 18 (our legal age), but nobody did anything illegal. So I'd have to sue the state which is crazy shit that takes 10 years to even start, and all I could theoretically get would be financial reparation which is just useless shit in comparison with 10+ years of the most important part of life.

It would be awful for anyone to never get to live their own life because of someone else's illness.

It is.
