HELP- Stomach bug tanked my supply

Well my 3 year old brought home the stomach bug straight from the pit of hell. Nausea, diarrhea, vomiting. Just when you think you’re feeling better, some more comes on out of nowhere. Hers lasted 3 days, mine is going on 5. Somehow my hubby has managed to escape the demon (my 6 week old too, thank God). I have tried to pump when I can but didn’t as often while I was sick (literally impossible). I tried to put baby to breast often but he just got a lip tie revision and is still relearned his latch. Day 2 of the virus I noticed my left breast felt tender and sore. There is no visible lump so I concluded there have a possible clogged duct. I’ve tried all the internet tips (massage, vibrating toothbrush, hot compress, hand express, I even tried dangle nursing). It feels a little less sore but still not normal! Also my supply has completely tanked. My OB called in zofran so I could rehydrate which gave some temporary relief to hold water down. I used to pump 6 oz both breasts, now I’m lucky to get 2 1/2. I’ve had lip and tongue tie issues with both of my babies and with my son, I’ve worked so hard on my supply through it all and it’s gone. Any advice? How can I get it back??
