I don't do comics, but I write. For me, I just enjoy getting my stories out there. I love the feeling of reading my work and thinking, "I wrote that!"
I especially love getting artwork done of my characters. When my merman character was first brought to life (character art), I was nearly in tears with happiness. Writing helps me to create the worlds and characters I want. If I couldn't write, I would probably lose my mind.
The only sad thing is I've learned people don't like my work, but I still love the stories I created.
