How did you keep going when you were at your breaking point?

I hate pumping. So. Much. And I'm so grumpy about it today!!! Need to vent and hear from other strong mamas.

I pump 6 times a day...should do 7, sometimes only make it to 5. I am a very slight under supplier and already giving LO (5.5 months) more formula than I'd prefer with combo feeding, so I'm not willing to go exclusively formula. We're close to starting solids and I imagine my ppd will decrease. So I feel like the end is near, or at least the end of 6 ppd.

I know I can do it, I just feel like I'm at my breaking point. What did you do when you felt this way? Howwww did you keep going?
