At 14, there is not really an acceptable reason for you to be "providing for your family". I saw in another comment that you said your mom is sick, but in Canada there are plenty of subsidies and things you can do if you're a parent and unable to work due to illness. I'm also assuming that since your mom is able to keep up with your child modeling career, she would be capable of at least applying for assistance of some sort. I would very carefully think about what your "attractiveness" means to you at such a young age. Be aware of your relationship with your mother and make sure you're not over valuing your looks because of her influence on you (because I promise looks get you pretty much nowhere later in life).

You won't get very far in life with such a closed off mindset towards other people's way of life. Did you know there's also a stereotype of people from big cities being uneducated and intolerant of rural people's lives? Which, to be fair, you are kind of showing when you say that rural Canadians have lower standards of "attractiveness" because they're not as exposed to mass media when the majority of Canadians do, in fact, have internet. There are plenty of examples of both racist rural people and intolerant city people. Learning to not judge based on stereotypes on either side is an important lesson that hopefully you will learn with age.
