Nagging wife

I'm looking for some guidance on Grace. I'm finding myself yelling and swearing mad at my husband who I love. We normally are not this way we are fighting lately and I am struggling with Grace. We've all been sick I'm sleep deprived also just had a miscarriage. I haven't had a second to myself. Because my kids were sick I wasn't able to get help and I'm a stay at home mom so I miscarried alone at home. I then got sick still not break. I'm finding myself losing my temper and no screaming at my husband. He works hard and had time for himself. When at home he's on his phone a lot. I'm finding myself so angry he isn't helping me. We went to a park for a walk and on the way home he didn't pull the car over and didn't realize I threw up all over myself and I just snapped on him. He went to the casino last night when he got home was 4:30 am and he woke the baby and didn't help me with him. Just went into bed himself. I'm just feeling like I'm nagging but I'm communicating asking pleading for help and I'm now snapping. I am really at a loss of how to stop yelling. I can't control him and his behavior but my attitude I know isn't helping. I'm being filled with resentment. Mostly are life is really good and we never fight and we are a healthy and respectful couple. I know we are in a tough phase of our marriage and I just want to know how I can stop approaching situations with a temper.
