Thanks to everyone who agreed with me that credit card fraud suuuuucks and wished me luck. Long story short, I had to open a new credit card and transfer my bank account, which led to complications such as, oh, not being able to pay my internet bill and coming home on Tax Day to finish my taxes and discovering I HAD NO INTERNET WITH WHICH TO FILE MY TAXES. But, after a quick trip to the building office to get my new FedExed card, a call to activate it, and a call to Comcast to get my internet back PRONTO, I actually did manage to get my taxes filed on time. Hurrah.
Things...things might just get back to normal soon. I hope.
