Struggling..

So while I was pregnant, I had anxiety and depression bad. My fiance just said that what I was worried about was irrelevant and nothing to be concerned about. Bills, health.. etc. Well I just had my baby girl December 10th via c section and im falling apart. Im a first time mom and this will be my fiances 5th baby. I wanted to breast feed and she wouldn't latch. I tried pumping and supplementing with formula but mentally I was struggling with pumping at night and trying to recover from my c section. Automatically I felt like was letting her down by not being able to keep up with the breastmilk. Now she's gassy and has been on 3 different formulas to help ease her but she is still fussy and screams at night. My fiance is constantly telling me what I should and shouldn't do but mostly in a smart Assy way making me feel like I cant take care of her. I dont feel like I have a strong bond with her and it breaks my heart. I know I should be happy but im struggling and my fiance acts like everytime I cry or am upset I am an inconvenience and that im pushing him away. I dont know how to have an open conversation with him without him being judgemental. We both have a lot of stress on us. We just bought a house and are struggling with bills. We are currently both unemployed so ontop of being sleep deprived we are stressed to the max. I just hate feeling like he could care less about my emotions or how im feeling. I hate feeling like im lettingnmy baby girl down and hearing her scream. Im just lost at the moment hoping it gets better soon.. and hoping my fiance realizes that im not trying to make his life a living hell by being emotional.
