Breastfeeding and formula!

I’m so annoyed! Initially I would breastfeed my daughter and then top it up with formula bcos she was always hungry and no one really told me in the hospital that the more she sucked the more milk would come! Now she’s a month and i wanna only breastfeed her and just give her one bottle maybe at night but I try nursing her for an hour an hour and a half and she will always fall asleep and after 10 min she will wake up and want more milk and then I just end up giving her formula! I even try to power pump and do t get more than 1 ounce no matter what I do! I try and try but nuthing I rilli want that satisfaction of her being full and happy with only my breast milk but I feel it isn’t enough for her and that just saddens me! Any adivice or anyone go thru anything similar?
