i am so done

i have tried everything, different flange sizes, different spectra attachments, soft silicone, hard flange, pumping cream, pumping spray and it all fucking HURTS. i pump 8 times a day. im so tired from not sleeping and i feel like im never being emptied on one breast and other produces nothing. i do not know what to do to make this easier.

my daughter is in the nicu and i feel like providing milk is the only way i can help her but im not even producing enough for her feeds.

any advice please because im hitting a wall.
