Am I screwed?
Exchanges are not a smart place to hold large sums of coins for extended periods of time.
I cannot believe someone who is able to have 164,000,000 coins would put it on an exchange like cryptorush and then go on vacation. Where have you been the last months (with all the news like mtgox, ...) ? Also how could you be a supporter, but don't put in your own wallet because you will not have any POS after 20 days. Or you are a liar or didn't think at all. Sorry to be so harsh but people have to learn it the hard way, otherwise cryptocoins don't move to the next level.
