If you have not yet received permanent resident status, then the divorce will only effect how CIS views future marriages from which you attempt to obtain an immigration benefit. If CIS believes this marriage was fraudulent (and solely for an immigration benefit) then they will more fully investigate future marriages.
I am sorry that yor marriage did not work out and that you were not married long enough, you need to make sure that you have proof this was a bonafide marriage so if you marry again you will not be accused of fraud. Be careful and take good care.
