I want to stop breastfeeding

I feel so selfish and guilty for wanting to stop, but it’s taking a toll on me mentally. Baby is only 2 weeks old and I feel like a human pacifier. I’ve tried pumping but don’t produce much after her feedings. She’s hungry all the time, and when she’s not she wants to use me as a human pacifier. This morning, I “fed” her for almost 3 hours. Every time she fell asleep on me/quit eating, I’d try to take her off and she was nooooottttt having it and was acting like she was still hungry. I kept dozing off with her in my arms. I feel really bad because I feel like I’m not doing enough for her. When I got discharged from the hospital they told us to combo feed just because my milk hadn’t came in yet, so I know she has no problem with a bottle. And anytime we do give her formula, she seems so satisfied and that makes me feel bad too. I worry about going back to work in march as well. Her dad feels bad that he can’t do much when she’s hungry. I love our bonding time, but i don’t know how much longer I can do the long mornings/nights where she does not want to let go of me :(
