Failing at breastfeeding 😭

Huge vent sorry in advance. My son will be a month old on Saturday and I have been breastfeeding since day one. He was over due, I got induced then ended up with an emergency c section. He lost ten and a half percent of his body weight before we left the hospital. I have been going to the hospital for weigh ins every week and yesterday he finally surpassed his birth weight. The first 2 weeks I was able to pump 4oz no problem but he was not gaining weight now I am pumping after each feed taking fenugreek and blessed thistle and drinking organic teas as well to try and boost my milk supply because the consultants think that my supply is low. The hospital has advised me I need to top up his feedings which I have been doing everything I pump after I feed I give right too him and he seemed to be gaining weight good last week but I can only pump 1 oz between breasts now. It's so hard to tell if he is actually getting enough from the breast. They are also making me feed him every three hours so I am constantly waking him up so he is cranky and so am I because I can't sleep it takes half hour to get him to settle enough to eat then an hour of feeding then I pump then give him the bottle with what I pump then by the time I get him to sleep there is like an hour before I have to start the process all over again. I am so miserable my husband doesn't even want to be around me, I wanted a completely natural child birth and got the furthest thing from it which made me feel like a huge failure to begin with now the one thing I wanted to do the most which is exclusively breastfeed is a complete nightmare and it seems to be getting worse not better! Anyone have a similar situation that ended up getting better without switching to formula. If I have to formula feed I will just feel so defeated I really don't want to do that.
