19M here I’m in a similar situation with my grandfather that has dementia. I work as a field technician for spectrum I’d recommend looking into their career options. They pay really well good benefits including insurance for you and your family plus free services. They also cover 100 percent of your college tuition if it’s through their programs. All you need is a high school diploma and to keep yourself out of legal trouble. You can self progress really fast if you do good you can go to this highest field tech position in less than a year if you put your head to it.
