Why does something always go wrong

I know I am not the only one who feels like this...I think? But lately it seems like no matter what I do to try and get ahead of things something always comes up. Once things at home get going good and seem to be moving in the right direction something come up whether it is with Lizzy, me or Chris something is always coming up. Then once that gets settled something comes up at work. Don't get me wrong I love my job and the people I work with. But my Chief has put me on a shift where I basically have to act as the officer in charge, which should be my Lt. but he doesn't seem to be doing his job and I am there to keep things together the way my Chief wants them to be run. And I have got use to doing it but between doing that at work and trying to leave work at work and home at home it seems like I never have enough time in the day to get everything done that needs to be done and still have time for me and with Lizzy and Chris. See Chris and I are both fire fighters and we work different shifts so we see each other two days a week and that's it. But the way work has been going I haven't been getting alot of sleep and then by the time I go the the gym and get home Lizzy is ready to play and wants mommy cause she hasn't seen me for 24 hours, so I nap during the day like her and Chris will take care of her but she just wants mommy, so I nap with her and then pray that she sleeps through the night.

I know that it is all part of life and having a family and working full time. But I just need a break and it doesn't look like there is one coming anytime soon.
