Horrible nipple pain

I've been up all night long with my little one trying to breastfeed her but my nipples are so sore it almost makes me want to scream as soon as she latches on. Its so bad that my reaction is to jerk away as soon as she latches on. So she isn't eating like she's supposed to and been up crying all night. Is there anything I can do to soothe them???:( I feel helpless and its upsetting me that I'm not able to feed her as much because of the pain :(
