Lost my milk

So

I woke up today with only about 10% of milk. Ive been trying to feed but theres just nothing coming out. Nothing when i pump either. Baby has never taken bottle n refuses it. He hasn't slept all day cuz hes starving.

Its neither a growth spurt nor clusterr feeding. Weve tried all the bottle feeding suggestions. Nothing works.

Hes already on week six of daily diarrhea

Wat can i do????
