I think I've just ruined my tablet while trying to root.

Okay, so I'm fairly new to this rooting scene, but I'm an Android veteran already. I've just used Chainfire's CF-Auto-Root on my tablet (P5220 running 4.2.2. Everything was correct.), and I forgot to check the Auto Reboot box in Odin. I then proceeded to hard shut down it, because Odin said reset on the UI. Cool. I turn it on. Now I got stuck on the Samsung Galaxy Tab 3 boot logo. I got worried. I then hard shut it down again by holding the power button, then I turn it on again. Now it's still stuck on the Samsung Galaxy Tab 3 logo. I'm scared I just bricked my tablet by trying to root it. I'm so stuffed.

Can anyone help me? This is my school tablet as well, and I'm basically ruined if it's dead.
