3 week old help!

My newborn will eat for ten minutes, fall asleep, I burp her and try and put her down. Less than five minutes later she will be fussing, then crying. I try rocking her but all she wants is to be nursed then sleep on my chest. She's been fussy like this for 24 hours. Her temperature is fine, and she's changed, not too warm or cold- what can I do? I can't co-sleep, that's just not an option. I'm breastfeeding and scared at this point because I feel like my boobs are empty..
