Pumping Help!

I have been exclusively pumping for almost 6 months now & lately the discomfort has been very unbearable. I have the spectra s2 & when I use the 24 mm flange, it sucks my whole areola in & when i use the 20 mm, it feels too small. i’m at a loss, because i want to give my baby breast milk for as long as possible, but i literally dread pumping. please help. 😭😭😭.

this is a 24mm

this is a 20 mm

even though the 24 mm is too big, i get more output than when I use the 20 mm.

it also bothers me when i pump because the plastic rubs on the bottom part of my boob.

i feel at a loss. ☹️
