It seems not matter what I do, I can't win....No one wants my art and i have only had ONE PWYW stream commission. I'm Just ready to give up at the moment...

Am I really that Bad as an Artist? I Just feel really useless at the moment and am ready to cry right now. I desperately need the money for my Wisdom Teeth removal but now I'm wondering is it even worth getting done if I can't afford it?
