I come from a family of doctors and successful people, so I'm considered officially the family's failure. No one in my family aside from my sister care about art, and comics, being "a lesser form of art", are considered something stupid. I was forced to study a career I didn't like but tolerated before I was allowed to study Fine Arts at a university. After that I had to spend over ten years working on things that had absolutely nothing to do with art. And you know where all that took me? To terrible years of depression and horrible irreversible mistakes.
At some point my family was forced to put an end to this situation because it became painfully obvious I just couldn't deal with it anymore and said "ok, whatever, go and draw your silly childish cartoons, we just don't care anymore". And so a couple of years ago I was finally allowed to quit my terrible jobs and was sent to therapy and started drawing and writing again.
It's been really hard because I lost practice after all those years. Also depression and all the other bad things that happened took their toll, and I had to start almost from zero. My art was inconsistent, I had no idea how to work with digital media and was terrified of other artists, because everyone was younger and more talented than me, and most of them just considered me "nothing". So I had stepped away from a cold world of people who thought I was worthless to fall where I wanted to be, but to still be seen as worthless.
My art is getting better with time. I'm still not where I should be at my age, where I would be if nothing bad had happened and someone had supported my art career from the start, but I'm slowly getting there. Now people know who I am, and other artists in my country are acknowledging my work. I get invited to conventions and art events, and I've gotten a couple of comics published in books (my pride and joy). I even put together a small group of comic artists here and we have an indie comics zine together. The Lonely Moon has even gotten a couple of fan awards and nominations.
If you have someone who supports you, be grateful. Even if they sometimes try to dissuade you from doing comics, as long as they still support you even if they don't agree, be grateful. Support can mean a world of difference, it can take you far and help you not to fall in dark places where you might get lost forever. If your mom/dad/lover doesn't like your art and frowns a lot when he/she sees you drawing, but still just lets you do it and buys art supplies for you on your birthday, be grateful. You can't force anyone to love what you do, but as long as they love you and respect your choices, you will be alright .
What I'm trying to say here is: don't get disheartened if people try to dissuade you. Some of those people actually mean you well and believe they're helping you. You know they're wrong but they don't. Be wary only of those who try to push their believes and choices on you and don't let you make your own decisions.
Watch this video, it's really powerful. Make anyone who tries to dissuade you from doing art watch it too if you can. And good luck, the world of arts can be hard sometimes, but stay true to your heart.
