I just bought $350 worth of coins at $28 each thinking it was going to keep going higher but then it fell. It is a sad day for me. 
Give it time friend, I sure hope you didn't sell yet. Especially seeing how networks like Mt. Gox are at roughly $13/BTC. Just give it time, BTC will rebound and you'll make your investment back. Remember, for the people who buy and sell this is the time when people are going to be gobbling up coins now knowing that it is capable of reaching highs of $30-$40/BTC. Once they start gobbling it back up, demand is going to be on the rise once more and the price will be driven back up!
Even if you just consider the difficulty that has risen dramatically in only a few weeks, or the people who will continue to swarm this network as they hear of other people's success stories or realize the potential of the Bitcoin beyond simply making a quick buck off it's exchange.
Believe me, it'll rebound, and it wont take long. Hang in there friend. =)
