I need help 😭

La

My son is 5 days old. He favored my right breast from the start, but the last day or so he couldn't even latch to the left one. My milk just came in a day or so ago and both breasts are very sore, but my left one is completely hard and way more swollen. It will occasionally drip milk but never enough for feedings and my son gets so frustrated. So I'm basically only feeding from my right breast and I don't know what to do. I tried pumping the left one and I got 1/2oz. in 20 minutes. Someone please help me, i just had a stunning breakdown. 😭😭😭
