When will it be Enough??

So, here I am. About three weeks away from being almost roommate free. The man is still driving us crazy and I am still so stressed out that my father asked me if I was doing drugs (which I am not and have never done). But what the saving grace is that yesterday and the day before my husband and I were cuddling in front of a movie and kicked our roommate upstairs so we could enjoy each others company. Yesterday we went to my parents condo in town here and had dinner with them and then they went home to the farm and it allowed my hubby to have complete concentration on his school. Work for me has been hell, lsat week I was pulled into my bosses office twice because of small mistakes. Nothing astromical just me not paying attention, which sadly in my job results in big mistakes. Lately I have been wondering if I am cut out to be a supervisor, lately it seems that the staff are telling me what to do instead of the other way around. But on the flip side, doesn't that mean I trained them correctly?? It's hard being a supervisor and seeing people who you would love to be friends with, but they can't seem to take you out of that role after the clock is over. Which I can understand, I would never go and have coffee with the director. I am new to being a supervisor it really has only been three years and let's face it, my "role model" isn't the greatest. I don't agree with a lot of what she does and says, but at the same time though staff listen to her. It seems that staff talk back to me more, is it because A) they feel that they can talk to me and express how their feeling or B) they don't respect me at all and deem me incapable of doing my job. Yesterday I am on the desk with my trainee and a co-worker, she asked him for help and he helped her but then needed to ask me anyway. Now, we are all helping customers at this point, my thought was "why did you ask him, instead of your trainer?". I am thinking that I am totally overthinking this and just trying to worry about something!! I mean let's face it I don't have enough stress in my life, but when will it be enough that I just finally break? At least then I can be off work for stress leave, or have a nice padded room :)
