need emotional support and prayers

I made an agreament with my exhusband to drop all back child support which was many thousnds of dollars for his help this last time around with chemo I think i made a deal with the devil. I didnt know him well when i married him i found out when it was to late i forgot how mean and evil he is he was fired from his job of 13 years and was 2or3 months behind on his rent so he asked if he could stay with me for 2or 3 months had him removed from my home allmost a year later the same thing as when we divorced trying to rip apart what i do have left. I made a choice to keep working and take care of our dughter untill I couldnt do it anymome i am now in stage4 of follicur lymphoma it was in 50 percent of my bone marrow untill more chemo hes so angry because i made him leave but right now i am really still down from the chemo i thoughht it was longer than a year ago untill i went to the hospital. now that he works at a job where his wages can be garnisheaned he wants our daghter so he wont have to pay child support really need your prayers to make me stronger to get through this again and this is on top of all my other promlems. He wont take care of our daughter i have listened to him talk about drunken vacations to Mexico empty beer bottles all over home over flowing ash trays filthy home no food in the ridgerator but 2 bottles of liquer pray he doesnt get our daghter. denise
