OMG WTF Work

Ok, so I love my job and I don't want to leave but I am stressing myself out way too much. I am in charge of scheduling people for their shifts which is not an easy job in itself but it is part of my job description. Issues with that include not being able to use certain people on certain days and people complaining about the shifts that they receive. Also, I have found myself getting to involved and not leaving on time. Unfortunately I am unable to be paid overtime so I have to short myself some where else which is near impossible since it is alway freaking busy. Like the last several days for example. I have stayed past my time pretty much every day since last Wednesday and it is starting to get to me. Like earlier this week, when I finally got myself away from my computer, I got into my car and started to cry. Not because I was upset but because I was so overwhelmed. All in all, I need to figure out how to leave work at work and not let it stress me out.
