Wow, you poor thing! The nipple pain sounds familiar to me, some mineral supplements may help, if you're in the SE area, PM me and I'll send you the name of my LC, she helped healps with my nipple pain.

Definately have a break - I've been through depression due to BF issues and just looking at your little bub happy & healthy, no matter if bottle fed or breastfed is the best way to go. Your MCHN can also help with PND and BFing and can activate help and support for you.

and all the best
