i hate myself for having art as a hobby

art has been the only thing I have ever been good at, I've been practicing for years and I thought maybe i can make it into a career but it feels impossible to do. My dad let me take Arts and Design tracks for senior high school but he doesn't even have faith that i can turn this into a real job, that i can support myself with it...I've been having doubts about this for a long time but I'm still not sure.

every choice i make turns out wrong and I'm scared this might be wrong too... i don't know what i should do, i regret picking up that pencil and paper in kindergarten, i don't even know if i like doing art anymore, it's just the one thing I've been doing for so long, I don't know what else i have to give...
