Default Accidentally formatted SDcard0, unable to mount or reformat sdcard0 or sdcard1 now!

I was attempting to clean up my SDCard1 when I accidentally formatted SDcard0. Now it refuses to mount and refuses to format.

I was on CarbonRom 4.4.4.

When I try to mount it says:

"Error mounting /storage/sdcard0/"

When I try to format it says:

"Could not format /storage/sdcard0"

Now it suddenly will no longer let me mount scard1 I have no idea what to do now!

I am at a complete loss, I believe it was formatted as exfat as I thought I was doing the external SDCard1. I am currently in CWM-based Recover v6.0.5.0 and have no idea what to do.

About the only thing I can do is choose "Install zip from sideload" and it seems to pop stuff up on my computer.

I just hope the phone is salvageable.

Any help would be appreciated.

UPDATE: Well, now the phone died and when I try to turn it on it gets the icon with the phone, the exclamation symbol, and the computer. I can't even get it into download mode. I might be out of luck now.

UPDATE2: Well I just said "Screw it" and plugged in the USB with that logo, odin detected it, and I unbricked back to GB. It rebooted and I am now in the setup screen, so I hope I am home free.

UPDATE3: I finally got it back to KitKat and it seems to be working fine.
