A woman got on facebook and said I was a theft. And just really trashed me. Do I have lawsuit?

How work as a bartender at the Erwin Elks Lodge and this woman was in there after they had the elections to vote to new era in which is exalted ruler and she accused the bartender's of taking money and I asked her if she was accusing me of being a thief and she said I said bartenders and needless to say I said something that wasn't very nice but the next day that I'm a theft and that I've dated every man or every officer from Mountain City to Greenville in order to keep my job and I was just wondering if I have a libel slander suit against her cuz she has really put my reputation out there
