Do all biblical scholars believe the world will end on May 21st?

Ever since I heard about this in January I have been FREAKING OUT, and now that it is May 3rd I am more scared than ever. Every night before I go to bed, I literally look up some sort of website to ure me and give me self comfort that the world will not end on the 21st of May, and then I am okay. Well.. I came across these videos on youtube.com and basically interviewed all these people who believe in it, and they started explaining how they did the math, and about all the 7s in the bible, and it's going to be 7,000 years after the flood, and that without a shadow of a doubt the world will suffer God's wrath on the 21st for 153 days until the whole world is destroyed completely on October 21st. I just picture my poor babies screaming in horror as all this goes on and the thought of it makes my stomach turn and I literally am getting an ulcer. It's all I think about it, it's all I dream about, it's all I look up on the computer. I am just so terrified that I don't even want to sleep because I am afraid the day will come faster. I have always been afraid of the end of the world since I was a little girl, but now I am even more scared than ever, and now that they ahve caught and killed Osama, I am feeling this huge sense that something even bigger is going to happen, and not in a good way. I just want to know ALL biblical scholars feel this way, or it is only Harold Camping that made this discovery. I know that it says in the bible that no one knows when the day will come, but I am just so scared that there are maybe some kind of hints and puzzles in the bible that we are just not reading close enough. I feel like I am goig to hell because I am not a christian (this is what they made it sound like on the phone call they gave me last month.) .. that I am going to hell because I live in sin, that I have children out of wedlock.. that I lie from time to time (to get out of going to work..) The idea of hell terrifies me beyhond my very core. I don't want to die.. I want to live and see my children grow and live and love and cry and be happy. Please people be nice.. I'm just a girl who wants to live and watch her children grow :(
