Guys help me ..

Ga

I've been sleeping all day , not eating much . Not doing anything at all. I'm super depressed. I was on Prozac for it before I got pregnant but had to stop taking it and I've been sad my whole pregnancy but I'm almost 8 months now and I'm just always crying and I'm super lonely. I'm an 18 year old girl living with her parents (out of high school) and the father isn't in my or my childs life. And I should be having a feelings of nesting and stuff but I don't . I'm just super over whelmed and I'm scared. Can someone help me.
