Feeling Defeated

I so badly want to breastfeed. My baby had a lip tie that we got taken care of and today began breastfeeding again but I just think I don't have what it takes and it makes me really upset. I want to hold my baby against my skin and feed him. But from pumping the past week my boobs hurt so bad because he clearly doesn't empty them both each time so I've got one or the other that's so full and hard and hurts so bad. I can pump enough to keep up with his needs and then some, but it is so time consuming to pump. I'm just feeling really down and don't know what I want to do. Guess I just needed to vent..thanks
