Feeling incredibly overwhelmed

We've hit a month of breastfeeding and I feel like I'm just constantly attached to a pump or have her attached to me. If she's not being fed, she's usually just yelling. Half the time I think she's just comfort nursing. She will not fall asleep unless I nurse her. I can't really go anywhere because she constantly wants to nurse so I can't seem to ever get enough time to pump. I can't nurse out and about because none of my nursing bras fit. I just feel like each day I'm getting closer to throwing in the towel and switching to formula and I hate it. I wanted to do this for both of us, and I feel like I'm failing at this. Not so much physically as I am emotionally. I can't be the only one out there feeling like this... right?😔
