what to do...

We are barley making ends meet on bills and without food stamps I Likely be without food I have a son 6 months and me pregnant. We have 8,000 something in debt and he buys stupid shit all the time what can I do I'm stressed to my limits it's making me contract so I have to be on bed rest.
