So I am trying to jailbreak my iPhone 5 on iOS 7 and it aint working.
Did the little installer and when I launched the app for the second time it just hangs and freezes.

I am unable to restore my phone because it says some bullshit about me not having enough space left.

What should I do?

You could try deleting evasi0n, and downloading the latest version again. http://evasi0n.com

For the restoring part, I don't know about that.

The only way is if you do a full restore. Back up all your stuff & do a full restore, (hold home & lock button, untill your phone turns off, and only release the lock button. Connect it fast to your computer. Keep holding home until you see a logo saying connect to iTunes) now try restoring your iphone.

As soon you have a fresh iOS installed, jailbreak it, then finally restore from your backup.

But if I jailbreak and then restore the jailbreak will go away?

Yes if you jailbreak and restore it will go away.
