Ughhhh I think I may have lice. I've noticed my head has become more itchy and I found a little bug that cracked once I pressed with my nails. I'll have to tell my mom in the morning. Can dogs and rats get lice from humans and vice versa?

I can't believe I have it again. The other two times I've had it, I was definate that I got it from my cousin. She had them and didn't tell me until I went home after a 2 week sleepover. I noticed that my head became alot itchier right after having my cousin sleep over (I figured it was excess sweat, dandruff or something..) Maybe she never got rid of it? Ugh...or maybe I got it from elsewhere this time.
