Well with that attitude you won't get anywhere xD
I say you should try to better your art in itself, cuz you know how many popular artists started off drawing horribly? Almost all of them xD

Ps
Not saying ur art is horrible just giving an example x3

I know. I'm just so worried about my future and with the way my luck has been so far I won't have much family to rely on if I take that chance at pursuing my dream and end up failing :/

I know this sounds like ungodly bad advice, but you'll never know you cant turn things around if you don't keep trying
If you fail, you dust yourself off, give life the bird, and put your effort either back into art or hit up your back up plan
I know we don't know eachother, i think i started following you through a friend, but i have been seeing you slowly slide downhill here and there. If you have a dream you have to keep pushing it and pushing it till it comes true, you can't let it die
That being said, it would not hurt to have a backup plan just incase you need to fall back off art for awhile
You have talent and you have potential, i know you can do something with it, but you've got to show yourself you can aswell

^exactly

Well, that's like anything in life. At one point you will inevitably have the option to pursue something and go forward or to fail miserably. Just a matter of if you let it happen or not.

You can always keep art as a hobby

There's nothing wrong with doing something to sustain yourself while you pursue art as a career. I'm taking a degree in animal sciences, and if my art career hasn't become liveable by the time I've finished the degree, I'll keep at jobs that the degree opened up for me, and work art on the side. The idea is that while my art career grows, I can cut back on time in employed work until I'm dependant solely on art.
Sounds farfetched, eh? I know. But it's not like people don't make career changes in life. I know I'd rather work towards a stretched dream on the sidelines to an employed career than give up on it completely.
