I'm losing my mind!!!

Do you ever feel like you can't handle another thing on your plate? Like, if the phone rings, you're going to explode? That's how I feel right now. I don't want to talk to anyone, hear anything, or solve any problems for anyone. I just need to do my homework and get some housework done. I know being a mom comes first but I'm about to lose my freaking head trying to get these kids to get along and do what they are supposed to do. AAAAGGGGGHHHH!!!
