So, everyday around five o'clock I feel very overwhelmed and weepy. I become very sensitive and simply put grouchy. Unfortunately, this is the time my husband comes home from work. Now I'm not quite two weeks postpartum, and I'm still healing from my c-section. Does anyone else feel like that this at a certain point in time during the day? I just don't understand. I'm very happy all day and crazy about my girls, but for a couple hours i just feel miserable.
