A new word for Exhausted

I need a new word for exhausted. Because I am tired of using that one over and over again. And most days it feels like that word doesn't begin to cover how I feel. Hubby being on night shift makes me feel like a single parent. I took the girls out of town for my stepmom's surprise birthday party, and they acted like they've been living in a cave and have never been in a restaurant before. Screaming at the top of their lungs, and running around. I feel like the asshole for having bad kids and I feel like an asshole for being mean to my kids. And we were all so tired yesterday, and they were just insane and I was too tired to put up with it. And I go to bed feeling like the worst parent in the world. I work full time, and we have a lot of things going on on the weekends, and I am fixing to take a night class in the Fall. Yes they are in dance classes, and yes we go to parties and things like that, but I see all these parents who do crafts and stuff like that with their kids, and that's just not me. I feel like such a lazy failure. I hate night shift because it exaggerates everything. Makes everything harder. The kids miss Marty. My 2nd daughter barely goes to him because she doesn't see him as often. And that saddens me. The kids are going to my parents this weekend, and I hope to get some rest and a new outlook on life.
