Personally, drawing for me is the source of almost every emotion possible. Joy, sadness, anger, hatred, love, and many more. I can either gain all these emotions while drawing or "splash it out on the paper". Ironically, drawing brings me both pain and relief.
It brings me pain, because I often jump too high in my expectations for a drawing and I get tense and sad.
And it brings me relief because I'll get to my expactations
eventually.
I don't want to give up.
I guess that's what you have to go through as a creative person.
