Stopping breastfeeding

Has anyone had to stop breastfeeding for their mental health? I just want to know if I'm not alone. I tried for 3 weeks and everytime she would latch it felt like a switch flipped in my moods, I could literally feel something of me change as soon as she would start feeding. Between that, cluster feeding, and pumping so my boyfriend could help with feeding her so I could finally get some sleep I couldn't handle it anymore. I feel so shitty because all I wanted to do was EBF.
