I just venting

I am a first time mom and the pressure is getting to me a little. My baby girl has become really fussy and gassy, I feel like a horrible mom because I don’t know if she is actually hungry or just fussy. I hate to hear her cry and I don’t know why. I’m trying to come up with a schedule so I can sleep, heal from c section, do homework, pump and be a great mom and i have not came up with anything. I moved back home to get assistance from my mom because her dad work 12 hours shift but grandma has her own life so she has not been a real big help. She does hold her for a short time so I can shower. Ladies I just need words of encouragement I feel defeated, I miss her dad but he cannot stay at grandmas house I’m not married. I feel really alone right now and I’m scared cause I want my baby to be healthy and happy. It’s moments when I look at her and realize this is what I wanted and I love every moment, she is my first baby and she is the most precious baby, I just want to do right by her
