Don't know what to do. ..

Baby boy has been ferociously eating for the last three or four days. It's four in the morning. I had to go get a bottle of milk I pumped earlier and warm it up to boob temp and he is finally asleep, but he will most likely be up in like an hour to eat again. I've tried pumping after he's done, but I think I was completely drained. He latched earlier and my boob felt like a soggy floppy silicone bag. He cried and cried for over 30 min, and when I tried to take it away or if it fell out he would scream like he was dying. My nipples hurt so bad. He's been such a good baby, never done this before. And my milk supply has always been really good. Now, I'm drinking mother's milk tea and water and thinking that maybe my boobs just quit. I pumped a little under four ounces earlier today, from both boobs. Usually I can pump 5 from each. I am really frustrated and just want to cry or something. Ugh
