I just lost my job and i have an alimony payment do i still have to pay or modify it

You should pursue a modification right away and at least on a temporary basis, for the period of unemployment, as otherwise you will still be required to continue making the payments per the last order that awarded alimony. It would truly serve your interests to consult with a family law attorney right away so that all the pertinent facts can be addressed and a modification pursued. All the best.
