I have to work with what??? in Life in the Lost Lane...

Good Morning there...Its always so very frustrating at work when you have people that dont want to work, help out and so on and so forth, well ive become this person. It pains me, but ive always been one to do my work with pride and to the best of my ability. But lately im finding that harder and harder. Oh we have a very busy area we work in, but once two of our co-workers leave you dont want to fill those positions, oh and you want to move our working hours around, we already have to be open 24/7 but you want us to perform over our ability with shit to work with. Yes, its very irritating, i didnt even hear them say this until my one co-worker leaving repeated it to me! What!! that just sent a wave of anger and emotional eating into effect. Grrrwl How am i to properly do my job if you make me work with the bare bones?? They tell us that in the past there was only one person that worked overnight and he/she handled it all, ya but we have everyone coming in from dental pain, pregnancy tests, STD tests, chest pains, abdominal pains, falls, car accidents and so on, im sure if you imagine to your hearts content they come in. I can only be super for so long before i have a mental breakdown and actually tell them what im really thinking. And if i did, people would be very shocked. Already along with all of that, we get treated like complete shit by some of the people that come in, dont treat me like shit because you think you are better than me. Okie time to go to that place im beginning to despise. To those that think this is BS...Yes i have a job, some dont, but these are my personal opinions. If i had the ability to just go and no have to work i would until i found a better job, but as of right now its paying my bills and that is what drives me to go in everyday. I pay my bills, i have my own insurance, i dont need someone to take care of me, i can take care of myself.
