Bad mom...

I feel like an awful mother. For starters I'm a stay at home mom, I dont drive due to personal reasons, and I'm by myself with my baby from the morning till night. My babydad works all day. I get so frustrated with my baby when shes constantly whining and wont nap. I just never have a break I'm literally losing my hair. I would never ever hurt her. But somedays I catch myself yelling at her or being rough when I'm rolling her over to change her or putting her in the crib alittle too hard. I just feel like an awful mom. I love her so much. I dont want to be like this.
