Simply not enough time

My husband asked me to night why I haven't been pumping this is what I told him:

I stopped pumping and breastfeeding and I still have milk. It was my choice to quit because of some very good reasons

Malnutrition, too much caffeine, not enough sleep and stressed out.

I work, and I'm like a 50s housewife give or take a few things away that they do. Granted I do work from home but my job is stressful most of the time. Not to mention I did take a week off from work and that put us in the hole by $400 this paycheck. I usually work enough to cover all bills. I'm tired and there are not enough hours during the day for me to take a pumpcation like I want. But I'm not healthy at this point so I do not want my baby to be caffeinated up and not get the nutrients she needs. I haven't drank water for about 2 weeks now and it's hard to let the caffeine go because I'm so sleep deprived. I have more than one child and they do sometimes help with the house work but I'm mainly the one that does it. What's a mom to do at this point? I want to breastfeed and she latches even though we are doing bottles. If I haven't had coffee that day I sometimes breastfeed if I'm not a zombie. But seriously how do I do all of this and still have time to breastfeed and pump without passing out at some point?
