Pumping

So I just had my baby Sunday; she came a month early. I have been struggling as far as pumping is concerned with the timing, getting a supply and honestly just taking care of myself. Since I came home, I'm stressed about the timing of trying to pump in relation to feedings and how the eff I am supposed to sleep so I feel well enough even to eat. When I'm not sleeping well-maybe an hour or so at a clip, Im not hungry and I know that is not helping with the pumping. Maybe this is a 5 am delirious post, but I need some advice. Im just so overwhelmed honestly i dont even know what kind of advice.
