Non citizen pregnant woman?

Hi I live in new york city. im 5 months pregnant and completly alone with no family support. i left my bf 2 months ago since i found out that he is a crack addict. he left without paying 2 months rent and I wasnt able to work that time. now i can. i saved my home in the last minute from eviction by court order. now im back to my work but having hard time to pay bills. im doing all my best to save money for my baby and me as i won't be able to work for first few months. i am not an american citizen, not even have a green card. I don't have a supportive family in my country and going back is not really an option. bf is a crack addict and 100% disabled to pay or support. I changed my phone# since i prefer to never let him back. i have no idea how to get financial itance for single moms in rent and rest of baby's and isngle moms needs. I recieved streight mediacaid and wic but i have no idea what this medicaed can give me except hospital bills and food stamps which im applying for. i also have seizure disorder... i was told that i can get disability but i am not a citizen. I would always prefer to work and not taking money from no one. but its seems like impossible not to.......any one familar with the law, any advice would help tons. thanks guys hoping to hear from you.
