Please call your Dr. and explain to him/her how you feel. It's very important that you do.
Please try to listen to some of the advice that these great mamas have shared with you. Your baby most certainly does not hate you. Please, please know that. Sometimes, nipple confusion can occur. You can work through it. Just have lots of skin to skin time, and co-sleep. Everything will be ok mama. Your baby LOVES EVERYTHING about you.
