Do yuo guys think my fã made character, "Kasey", is boring and dumb?

I wanted to know what you guys think because this morning, I was planning on making a special a new animê fã fic, but someone, "Forsaken Outcast", told me that my fã made character's name was dumb, stupid, and not to mention boring! :'(((((

It really hurt me bad and I worked so hard to come up with this story and fã made character.

I want to know what you guys think...if it's dumb, you can say it. I'll try not to overreact.
