Taxing over taxes

It's already the 12th of April and we have about 18 days to submit and declare and pay our taxes to the govenrnment. And I have no idea how to do so. I tried looking the info on the Net, and all I got was mumbo-jumbo which might as well be Greek. Okay, so I took some time out and read and tried to take notes of the whole situation, but nowhere did it mention what to do if you're new to this whole paying taxes thingy. I mean, I've never paid before and I don't know the difference between Forms B2002, B2003 or B2004 or Potongan Cukai Berjadual or whatever. I believe I don't even have a Borang Cukai Pendapatan. I probably don't even have a file with the IRB! So where do I begin? What am I to do?!? Aaaaagh, this is so frustrating!
