Do i have a right to be mad at my friends for doing this?

I'm on vacation, so I'm missing a whole week of school.
A few of my friends decided to pull a joke on me.. We'll call my friends Nicole, Jo, and Christine. So, Nicole Jo texted me after school saying that Christine went to the hospital because Jo...

pushed her causing her to fall hit her head on a table. Now, they said they were just playing around. Christine is my best friend, btw. So I went like 9 hours without texting Christine, because think she was in the hospital, she couldn't text. So then she finally texted me we talked about what happened, but she said she couldn't remember anything. Then she ended up telling me it was a joke and Jo said they didn't think I'd believe them. I have a right to be ticked off at them, right? I mean, they went too far with the whole hospital thing which had me worried. So, I have a right to be, right?

yeah you do. but now that you realize its a joke its time to move on and realize they pulled a good one on you
