The struggle is real

Hello everyone. I'm a first time mom, and had preeclampsia so they HAD to deliver my baby boy at 27weeks (he is now 10days old). I AM STRUGGLING IN PRODUCING MILK. 😭😭😭

I didn't really felt the pressure until the lactation nurses kept calling me about how small amounts I am producing, now I feel like I'm suffering from depression or something. The most I was able to pump was 20ml. They say to pump every 3hours to stimulate it, so I do my pump in the morning and I would get maybe 10ml or less, then the next 3hours nothing. Just like 3 droplets and it's so frustrating coz they have to give my baby a donor's milk. 😭😭😭😭😭

Any recommendations on how I can produce more milk????
