I give up! I'm a bad mom!

I wanted kids for sooooo long but I never knew how excruciatingly difficult and lonely  being a mother is going to be! When my husband and I discussed having a baby he said he wasn't going to be able to help much since he works long hours almost every single day. I said that's fine since I'm 30 years old and I don't want to wait too long before we start having kids. Since it's our first baby, my parents told me to stay with them in my hometown 5 hours away so they can help with everything at least for the beginning. The first 3 months were tough but my parents made it so much easier. My husband said he missed us too much and I thought I could handle it on my own so we moved back. It's been two months and I feel like a single mom! I don't get any help during the day since he's at work and at night he just gets frustrated that the baby is loud. The baby hit the 4 month sleep regression and has been so difficult. I feel like I'm at a breaking point! I want to move back home where my parents help, where I have childhood friends that have kids, where my job said they'll take me back, where I can breathe again! I just want to give up so badly!!!! I love my husband and we have a wonderful relationship but he's an awful father/partner when it comes to our baby. I know it's not his fault and that he told me he didn't have time to be a father. But I'm just so frustrated! And I know our marriage is suffering by how unhappy and resentful I've become. I want to move home!!
