Genuinely scared of my 1 month old waking up

I’m a first time mom to a 5 week old baby girl and I love her to death but every time we get her to sleep/nap I get so scared about her waking up again because all she does is scream. She is incredibly difficult to get to sleep sometimes and then when she wakes up, if she’s not actively eating, she’s screaming. We have her on a sensitive stomach formula but she still has a ton of issues with gas, even when giving her gas drops. I breastfed her in the hospital but she was having a lot of difficulty with latching due to a pretty severe upper lip tie so once we were home I pumped and gave her breastmilk in a bottle. That lasted until the day before the 3rd week and I had to switch her to formula because pumping and bottle feeding were really wrecking my mental health (she was still having tons of gas issues even with the breastmilk and she was still constantly screaming, which made pumping even harder because I was constantly having to hold her). It makes me so depressed because I feel like all I’ve ever wanted was to be a mom and now that I am one im miserable and I feel like I’m not even able to fully enjoy my baby because she’s just constantly uncomfortable and upset and I don’t know what to do.
