I had something similar.
I really struggled so so much with breastfeeding. The hospital were really shit at supporting breastfeeding. One midwife actually told me my nipple was too big and I had to formula feed which was absolutely not true!!!
When my baby latched on it was SO painful I would dread her waking up for every feed. I was also a crying mess. My husband said his only memories of the first week was me constantly hunched over desperately trying to breastfeed. I had a csection too so I was so out of it drugged up and in pain.
My baby would also constantly cry.
She lost 13% of her birth weight and from then we topped up with formula after every feed. Looking back I feel so guilty as she was so hungry. I wish someone had said to me breastfeeding did not matter and to just feed the baby. There's so much pressure to breastfeed and so much conflicting advice. I would literally sob thinking I was a terrible mum that I couldn't do anything right and the one thing I had to do was feed my baby and I couldn't even manage that.
Luckily my husband spotted how much it was affecting my mental health and encouraged me to stop breastfeeding which is exactly what I needed as it was affecting me so much. The health visitor was the only healthcare professional that said it did not matter as long as baby was fed and that she had seen many mums have mental health issues because of breastfeeding and it just isn't worth it. That really resonated with me for some reason and made me see it in a different way. Please please don't put so much pressure on yourself. I've been there and it's not worth it and takes away the enjoyment of spending time with your baby.
Turns out she had a posterior tongue tie and a shallow latch. I asked multiple midwives to check for tongue tie and it was only diagnosed when I saw a lactation consultant
But by then I had blocked ducts and mastitis because baby wasn't draining boobs effectively and I was so out of it needing sleep to pump frequently
I also struggled when my husband went back to work to pump. I was essentially triple feeding which took up my entire day. So nursing, then bottle feeding (formulanor breast if I had enough stored) then pumping.
It really wasn't sustainable and really hard as I did this throughout the night too.
Then I went down to nursing only if I felt like it
Now 10 weeks in I'm still pumping but only 3 times a day not after every feed as it's impossible to keep up and enjoy my day/ time with the baby
It has made a huge difference and I dont feel so bad about formula feeding now. Baby gets the benefits of a bit of breastmilk and has a healthy happy mum.
If I hadn't stopped breastfeeding I feel like it would have been a slippery slope for my mental health.
Please don't beat yourself up. You're a great mum and it's not worth losing your mind over xxxx
