Sabar sabar, mastitis ni memang stress gila especially kalau ada milk supply issue on top of it! A few of my mum friends kena juga and they said the antibiotics really do help within a few days, so hopefully yours will turn around soon, just make sure you're finishing the full course even if you feel better. The main thing is keep draining (I know sakit but it helps), rest as much as you can, and maybe try warm compress before feeding or expressing. Stress jugak memang boleh affect supply, so try not to overthink it too much (easier said than done, I know!). Kalau after antibiotics still tidak ok, just follow up with your doctor straightaway, they'll advise you on the next steps. You've got this, mama!
