All alone

My sons father just left us. I don't know what to do. I don't have anyone helping me. Nobody. I have no job I haven't finished college I have nothing. I don't know what to do. I need to work but who's going to watch my son? He refuses formula and I don't produce enough to pump. Everything's a mess. I'm a mess. I don't think I can do this. I don't know what to do. I don't know what to do I don't know what to do. He threatened to take my son if I file child support and he doesn't even have a job for child support to even take money. I don't know what to do. I don't have anything my son deserves better. I don't want to lose him but I can't do it I have nothing I have nothing and my anxiety and depression have only gotten worse. I'm the worst possible person for him to be with. I do t know what to do.
