Go to your local Medicaid / Social Services office (that's what its called in NY) explain your situation most likely they will put you in emergency housing which may be a shelter situation for a while & set you up with medicaid. It's not a pleasant option & will be a reality check but it is what it is.
Go live with the baby's daddy and trust me she would miss u call u back tell u how she's sorry and things like that....but good luck hun
Can you live with the baby's father?
Explain to her that you have nowhere to go see if she will let you stay till you find somewhere and hopefully she might by then be abit more understanding good luck x
