Predominantly Me..

Blogging from office.. I just wanna cry!! when I'm about to finish, the comp hangs on me & I have to redo the whole formula sheet for 16,000 rows.. I have to wait 30 mins for the file to be opened & each time I copy over the formulas, I need to wait for at least 15 mins.. still waiting for the updates now.. hopefully its successful this time.. I don't wanna camp in office.. why am I so down on my luck??? I wanna cry!!
