Over a month in and I hate it

When I got pregnant I exclusively wanted to pump. For some reason I cannot remember I started out breastfeeding. Now a month in all I can manage is one (maybe 2) pumps a day between all of his feedings. Thing is, I hate breast feeding. I do it out of fear of not having enough milk when I pump but I just hate it. I feel so attached to the baby with hardly no break.  It is making me want to go back to work sooner.
