I'm going to court in GA for a divorce on the 1st. Any helpful advice?

[Scott C]

I'm going into court for a divorce in Georgia on the 1st of April. Can't afford a high dollar attorney. It really doesn’t matter I just about gave her everything anyway. She going to try to get me for child support even though she had a man move into the house (who is still with her by the way) the day I moved out. My house went into foreclosure and her family bought it out from under me. She's done drugs, did them with my oldest Son and has been seen in court over it as they put her on rehab programs and my oldest son just went back to court as he was caught with pot. Do I owe child support? My oldest Son has no respect for me and has nothing to do with me. The have a history of taking the money I've forked over for child support and using it god knows what. I haven't paid anything in a while. I'm presently seeking employment and am down to my last dollar. What can I do, and what can I expect? Is child support in order,am I free of it or will the judge make allowances?
