Supply drying up after mastitis

Hi mummies, I had mastitis more than 2 weeks ago, and my supply dropped significantly from 1000ml+ per day to currently 700ml+. I've not been able to get it back up even though internet sources say most people do 😭😭😭 anyone experienced this before and what should i do? I'm heading back to work this week and this is causing me lots of stress... thanks in advance!
