Nonstop crying

My 6month old cries all day, and I can't figure out what to do to stop it. She's showed no signs of pain, the doctor has said she's completely fine, she has plenty to do, she's fed and changed plenty, I just don't know what to do. Is this a thing everyone's dealing with right now, or just us? We introduced binkies about a month ago because we thought she was teething. It helped for a little bit, but she's right back to crying nonstop unless she has a binkie or she's drinking formula. I noticed she cries the hardest when we lay her down- not just for naps, but I'm talking diaper changes, playtime, or to watch something. (And no, she's not overstimulated by shows, so please don't mention it. We do screentime but I heavily monitor it.) It makes me feel horrible setting her down but I have chores to do, and I can't sit with her in my lap 24/7. But the crying has really been getting to me the past few days because it's ALL DAY and any time I think I can finally sit down for a break, she cries again and I get up to try to calm her down. I'm really struggling, any suggestions?
