Have no idea what to do

Last night my wife of 13 months stated, after a 6 hour discussion, that she wanted a divorce.  During our marathon, I said that while my rational mind knows we would never work out, I made the decision to get married and I felt I had more energy to give to the situation.  I know this is stupid, but I still wanted to try.  I felt like we gave up too quickly.
  Granted, from the start we were opposites with different financial backgrounds and ideas of responsibility.  I was blind and in love.  Well after about 8 months of marriage she was fired from her job and that lead to many arguments about responsibility to the family, one another, and what the right way was to solve the situation.  It wore on us both.  I was considered the parent (telling her what to do) and she was ostrich (burying head in the sand in hopes of better days with little effort or planning).  Regardless, I can't sleep now.  I feel very lonely, as I moved to this city to be with her, and don't have any friends.  I have my parents, but they can only handle so many 4 am wakeup calls.
  She seemed so cold when we were talking and said at one point, "I want you to hurt right now, because you've made me hurt."  She brought out resentments against me that I never had heard before, like about or wedding, and ones I had heard.  The disconnect from us was really sickening and I don't know what to do.  Thinking of investigating online divorce filings, where you answer questions, they send you the forms to take in to the court house, then supposedly you just go to court.  Anyone know if those work. 
  Sorry this is so long, but I just feel like my head is rambling.  I start a new job in 2 weeks and I'm afraid I'm going to screw it up due to the stress and sadness I'm under.  I feel stupid, sad, angry, etc....Please help if you can...
