Help me please, I don't know what to do!!

So I had flashed Jelly Bean unofficially onto my Verizon Galaxy Nexus back in July, and everything was fine. Then, just yesterday, I hear that it has officially been realeased. So I tried to flash back to ICS (I made a recovery of JB just in case) and I'd just update from there. It gives me an error that /data couldn't be restored, so I thought I'd just go back to JB which I'd just backed up. Same error! So I looked it up and found it might have been that I didn't turn developer options off. A few hours of fiddling until well after 3 in the morning, and I now have multiple issues. CWM gives me an error that it can't mount /sdcard, the bootloader has a little error at the bottom that says "FASTBOOT STATUS - FAILInvalid Command when I plug the phone into my computer, and I can't boot into ICS or JB. I really need some serious help. Thank you to anyone that could possibly sort this out!
