I need to know about getting alimony re-instated in the state of georgia. anyone know anything about this?

i was married to a man for 35 years until he decided he wanted a woman who had received a large insurance policy from her dead husband. i was receiving a decent sized alimony until this man (actually it was his new wife who was paying it) decided i didn't deserve it. they got an old judge who was going thru a divorce himself so i got the shaft from the judge. the only thing i did wrong was to take in a boarder because i needed extra money. they made it look like i was co-habitating which i was not. i was taken to court and subsequently lost all my alimony. i need this badly now as i am in a position where i cannot work due to recently having total hip replacement surgery. also, while i was in the hospital the finance company repossessed my car. i am 72 years of age and in good health except for the hip replacement which is getting better every day. need some help and good advice about re-instating my alimony, if possible.
