Please read this in its entirety and answer, it has to do with tomorrow being Judgment Day, I'm nervous?

So, as I'm sure almost everyone knows. The founder of Family Radio, Harold Camping, has predicted tomorrow, May 21st, 2011, to be Judgment Day which will be heralded by a massive earthquake. Now, this same person, Mr. Camping, has made incorrect predictions about this same thing, I believe, back in '94, '95 and I think even '96. Though, he blames it all on a miscalculation. Now, for all of those who are Christian and even the ones who aren't, if you are supposed to live your life by what the Bible says, then we can obviously quote the books of Mark and Matthew when Jesus spoke, "But of that day and hour knoweth no [man], no, not the angels of heaven, but my Father only." Now, being somewhat a Christian myself, I'd prefer to believe this because it is, after all, the "Word of God." However, people argue against this saying that it doesn't mean no one can know, only that no one does. Therefore, they use that to justify their predictions. I also know that the Bible claims that if a prophet claims something by the Word of God that does NOT come to pass, ignore him, because he's obviously a false prophet. So, Mr. Camping has been wrong a few times before on "Biblical Proofs" he claimed came directly from the Bible, right? However, he was wrong, so, would that make him a false prophet? Anyway guys, I'm REALLY scared and I don't know why. Everything in my mind is telling me NOT to believe this, yet, I'm freaked out about it for some reason. . .I want to think I'm "smarter" than this, but I'm still scared. Can anyone give me their honest opinions on this matter and tell me if I should be scared or not? I don't even know if I'm truly saved. . . not to mention, half my family and friends probably aren't. Please give only your honest thoughts and take this seriously, to be honest, I'm freaking out right now even though I know I shouldn't really be.
