I tend to agree with your mom to do something short and cheap like an associate level program at a community college that could provide you with a marketable skill. If those things that you love aren't high earning skills (save if you turn them into a business - but do you have it in you to be a business owner/entepreneurial?) then we can aim once step down -- what are those career fields that you think you can stomach, that also pay fairly well?
What is the reason that you couldn't complete your nursing cert?
Medicine seems to suit you based on what you would describe a meaningful work environment/career. Here is a video on medical careers that pay well, and the video starts off with qualifications that take within 1 - 3 years to complete.
The CNAs and RNs in my country make joke pay (I am talking worse than call center workers), that's why the ones that can afford to leave the country for greener pastures in countries that will pay them well.
The predispotion to a caring profession is obvious, with the dominance of water in your chart.
