Maintain supply but also mental health advice please?

Hi all, I'm 6 wpp and really struggling. Breastfeeding was horrific with the latch and baby ended up back in hospital after being discharged 4 days with low blood sugar due to lack of feeding. I made the decision to express and currently do it 7 x a day and we've started topping up one formula feed. In some fairy tale world I'd still be able to pump 3x a day and give her one or two breastmilk bottles for a few months...

Is it possible to do this by perhaps dropping the MOTN pump first and just do 5-6 in the day? From reading a lot it's probably the worst one to drop but I'm so sleep deprived and mentally tapped out that i feel dropping it might help - so last pump at 10.30/11pm and first one around 6/7am?

All you mummas out there who do this for months on end, I truly have so much admiration for your determination because honestly I cannot do it 😭
