Breastfeeding is hell (just ranting)

I’m almost 4 weeks PP and breastfeeding has been complete hell for me! My baby has had a shallow latch since birth and I have very flat nipples. I’ve seen 3 different lactation consultants. She has a tongue tie so we got it cut and it helped a little but her latch was still shallow. At 3 weeks I was sick of the constant pain and my breasts were so engorged because she never completely drained me. I decided to start pumping and bottle feeding. My baby was way happier and had a full belly and started sleeping way better. However I ended up developing mastitis 😩 last night my left breast was in a lot of pain but I didn’t see any redness. Then at 2am I woke up with extreme chills and I was running a fever of 103! I couldn’t get out of bed without falling over. The whole right side of my breast was bright red and hot. I called my OB and she called in an antibiotic. I almost went to the hospital because I felt like I was literally dying but I knew they’d put me on the floor with covid positive patients because my temp was so high. I don’t even know how I got it. I want to give my baby breast milk so she can get my antibodies but this has been a nightmare for the last 4 weeks. I know formula would save my mental health though 😭 I’m just hoping that this gets better for me eventually
