Breastfeeding support

I know I want to breastfeed her to a year. I'm already 6 months in & she does amazing. Shes off the charts for her weight & is very healthy. But I'm so sick of her biting down on me. She wont sleep in her own bed, she has to lay beside me with my boob in her mouth all night. I'm currently suffering from a milk blister & clogged ducts in the left. The right isnt producing very much milk right now. So ive been power pumping & eating all this nasty crap trying to get my supply back up. She won't take a bottle 😫 I'm ready to try out some formula.. I hate to say it but no sleep, plus the problems I'm having, on top of her biting the blood out of me.. I just don't know if I can go another 6 months.
