I feel like I’m not a good mother

Please no mean comments, I don’t think I could handle it right now.

I just had my first baby on the 26th. I love her so much and couldn’t imagine life without her now that she’s here, but I don’t know what is wrong with me. I’m so exhausted and have been ever since I was in labor. I try to rest when she does but it’s hard for me to sleep bc every little sound and whimper she makes has me jumping up to check on her. I’m young and still living with my mom and she helps me as much as she can and even encourages me to sleep while she looks after the baby. I feel so guilty when I actually do let somebody else watch her and just sit and cry instead of sleeping. Sometimes I break down and cry while feeding or looking after the baby and that makes me feel bad too. I feel like my baby can sense how upset I am and won’t love me. I don’t know what to do or how to feel better. I feel so tired 24/7 and if somebody even looks at me wrong I break down. I just want to feel better and be a better mom to my baby but I don’t know how. I’m afraid to mention this to my doctor too bc I don’t want to hear it confirmed that I’m not good to her. I love her so much and wish I could feel better about myself for her.
