What do I do

I had my second son May 13th and I am so so happy he's here. I'm currently breastfeeding and it's going great but we are having money issues and other things stressing me out and making me become depressed, all tracing back to us having a hard time affording anything. The way I'm feeling is making me but want to eat so my older son has more and to be honest I just have no appetite, I just want to stay in bed and cry. I can't go to the Dr for help either, I have no way there. I know the more I don't eat the lower my supply will get and that makes me more depressed. I don't know what to do. I have no family that can watch my son's so I could work too help with money and if I did we only have one vehicle and my husband has to have it. We're drowning and it's killing me. What can I do? Where do I go? We're in Georgia if that makes a difference. We have WIC but it doesn't help with much... Is there any way to get assistance with childcare so I could work? I don't know what to do and the only thing I want to do is call in bed with my sons, stay in the dark, cuddle them and cry...
