Swollen, sore breasts 😣

Hi mamas, Please help me with your experiences! 😔 My baby is 7 days old today, since my milk started to come in around day 3-4, my breasts hurt so much, there’s huge lumps in them that I tried to massage out under the shower with hot water, I tried to pump as well because I read that I have to pump after every feeding and “empty” them otherwise they would get blocked and I could get infections etc but it just won’t stop, I pumped for hours and milk was still coming and I just got tired of it and washing the pump’s bits and pieces after every use 😩 So now I’m not pumping after every feeding. And I also read that if I keep pumping my boobs will make more milk so once I finished pumping on one side and my boob got a little bit softer, the other one is rock hard and hurts and leaking. I pump it and half an hour later the other one I pumped before is the same again, rock hard and hurts. And the lumps won’t go away, and I’m so tired to pump or to do anything, I have the baby blues, some problems in our relationships and I could just cry... 😢 Any advice ladies?? 😣😔 How do I regulate my milk supply?? And how do you wash your pumps?? 😔

I’m a first time mom and a bit lost right now 😔
