Pumping is so depressing

I know I shouldn't compare what I pump to others, but it's not not to when I can only pump 2 oz combined from both breasts. I'm going back to work in 6 weeks and really want to be able to have a nice stash of milk for my LO as I don't want to give her formula. For the first 6 weeks, I've been exclusively breastfeeding and pumping occasionally. Now I'm trying to get on a pumping schedule so I can produce more. It's just so much work between breastfeeding and pumping. Ugh!
