am I a bad mother?

I'm 6 days PP. Just had a beautiful little boy. I'm exclusively nursing and currently off work for my maternity leave. Around 34 weeks pregnant I was diagnosed with gall bladder disease, sludge, and stones. This cause extremely painful flare ups and I was put on a very low fat diet. They wouldn't touch me or operate during my pregnancy which is understandable so I stuck to my diet, but this hasn't gotten rid of all of my flare ups or attacks. Today, I had a terrible flare up, I'm in pain and feel that's it's been hard to take care of my newborn through the pain, but still I have. My took me to the ER in hopes that they can actually do something for me now that I'm no longer pregnant. Although definitely not ideal, We brought our newborn along as I'm exclusively nursing and don't have anyone to watch him. We came in to an almost empty ER waiting room and sat in the far corner to wait, with his car seat covered with a blanket. When the triage nurse called me back to get my vitals taken she asked me about the IV marks in my arm and what they're from, to which I told her I just gave birth 6 days ago. She proceeded to make me feel awful for bringing my baby here to the ER. I understand her concern as I have the same, but she continued to tell me my husband should take him out and away while I'm here. I explained that I'm nursing and don't have a choice and she continued to say he shouldn't be here. I walked back to my husband crying. I have to be taken care of, and I don't have any other options but I'm feeling guilty and like a terrible mother for having him here. Am I awful?
