Tongue tied

Had my baby November 20th weighing 7lbs 14 oz 😊. I feel incredibly blessed and so grateful. I strictly want to breastfeed but I feel like my little princess is having a hard time. My breast hurt like crazy, nipples are cracked and sore making me want to scream every time she latches on. Pediatrician came in to check her and told me she is tongue tied 😢. Anyone else ever had this problem and did breastfeeding successfully? 
Good luck to all of you 🙏🏻👶🏻❤️
