Officially giving up on breastfeeding..

Baby girl will be 3 weeks old.. Idk what happened but nothing is working out. I used to pump every 2 hrs & would get a good 6-8 oz & she drank 2-2.5 every 2 hrs. I got a bigger flange because my nipples were really red & sore from the 25.5 so now I'm at a 28.5 mm. I pump for 30 mins & can barely overall get 2.5-3 oz.. My nipples hurt so bad, they are so red & swollen, I have a HUGE lump from what I assume is a clogged duct, which is extremely painful.. This is honestly just very exhausting & painful for me.. I'm ready to give up & give her formula.. I wanted to try to exclusively breastfeed then pump for at least the first month but I don't feel like I don't have it in me.. My milk supply wasn't amazing but it was enough for her feeding & a bit to store for future feedings but now I'm barely producing anything.. I have tried drinking as much water as possible, taking fenugreek supplements, oatmeal, massages, etc. Do you ladies have any tips or advice for me? 😕
