I hope everything get's back on track soon! That was pretty fucked up what happened there, I'd say you have a pretty good case against the realtor and/or landlord.
...and hopefully your back recovers well!
Lately is seems like almost everyone in the whole fucking world is either dealing frustrating stupid shit, or horrible depressing events.
I will look at this as a reminder that life isn't just randomly fucked up, it's universally fucked up.
