I’m so DONE

don’t get me wrong, I love the bond me and my child have because of breastfeeding, but I’m ready to switch to formula. Breastfeeding is becoming very hard and stressful for me, and yesterday all of a sudden my supply dropped down and I have no clue why!! My only issue is, my babe will NOT take a bottle. We tried a sippy cup but he just spits it back out! So I feel stuck with breastfeeding, and it’s really wearing me down. I can’t go anywhere, or have any alone time, and with this seasonal depression it’s really kicking my ass. Any tips to help a lady out? Did anyone else make this transition with a stubborn baby who just wants boob? (Also want to add my baby is 7 months old and will not fall asleep unless he is nursing).
