HELP ME ! 🙁

okay so i had my baby girl on september 22nd 💕 i tried to breastfeed her but it was so painful i had to supplement. i went to a lactation specialist and we decided that i am just too sensitive to breastfeeding her. i have been pumping and supplementing. i am gonna try my hardest for as long as i can to give her my breast milk. the problem is that i am not producing shit ! at the most i produce 2 ounces all together after pumping for 30 minutes each breast and thats after waiting like 12 hours to pump * i normally pump every 4 hours *. i am feeling so discouraged, disappointed and stressed. what should i do to get a milk supply ? please help me 😟
