Please help me get a home

I am homeless, pregnant and alone . I am trying to get an apartment but don't even have the money to eat day to day. I steal my prenantals and the things I need for my pregnancy. And I sleep behind store buildings so no one will see me and try to hurt me in any way. I have applied for shelters but they all are either full or have a waiting list. I am trying to enroll into college but cannot without a stable address and healthy hygiene. Please help me I am at my last resorts . I do not do drugs and do not drink alcohol and are willing to take tests to prove it. Just trusted the wrong people in life. Now I'm fighting trying to save my life and my child's life too.
