Overreacting

So I know I'm probably overreacting to this whole situation, but I am ABSOLUTELY devasted at my computer. I feel like I can't breath and that I'm going to vomit every time I think about it. I mean, I guess it's nice knowing that I'm going to be getting a new computer in the next few weeks, but I honestly don't care. I would rather spend the rest of my entire life not using a computer if it meant that I could have my hard drive back. I have hundreds of dollars in downloaded songs, another couple hundred in downloaded applications and programs, and how do you place a value on the memories of the last three years of your life? Every picture I've taken in the last three years was on my computer, and I had no way of backing them up, so no - I have no back up - I know I should have done something - and thanks for reminding me - but no that's not helping me any. I still feel like I've lost someone in my life that I deeply cared about, not my computer, I'm not that ridiculous - but every picture, every memory, every graduation memory, every picture I had of my niece when she was born, every picture I had of my grandfather in the last three years, my brother's wedding - I could go on and on and continue to cry about it... I'm absolutely paralyzed and have no idea what to do about it....
