Feeling guilty 😕

Not sure if this is the right thread to post this but, my LO couldn't latch in the hospital because of his tongue tie. We are going to get it fixed but haven't yet just because we have been so busy at home getting into a rhythm. He's almost a month old and I was pumping and supplementing with formula because I couldn't pump enough to meet his demands. Well I went one day with only pumping once and my supply has gone down so much. But I honestly am feeling mixed emotions about it. On one hand I feel like I failed him at breastfeeding because I could have tried harder. On the other hand I'm relieved because I don't have to worry about pumping every couple hours and I can spend more time cuddling and playing with him. Has anyone else gone through this? So far its been two days without pumping and thankfully I have no pain and I'm so much happier.
