I know they hurt really badly. I'd be scared, too, but, I'm also a sissy. It's not the end of the world kindof pain, but, I've heard it definitely hurts. My brother (who's 31 now) had leukemia when he was five to ten, and, he had to get them all the time. And, my mom said it was so hard to be there and watch a little kid like that hurting so bad. And, he had to get them ALL THE TIME. But, you will be fine. I won't even tell you to be strong, cuz I know I'd be screaming and crying like a big baby. I'll be thinking of you!
