Job hunting again...

I am on the hunt for another job. I like my job but I am ready to go. The lady that I work with is planning on leaving to go back home to Louisiana which means I am going to get stuck with all of her work plus I am going to have to work with a new person and I do not know if I can handle it. She says she is planning on leaving in July so I am hoping I can be gone by the end of June. I put in an app the other day for the same job that I am doing but at another facility and I hope I can get it. Right now, I am just waiting on getting a call for an interview but if I can make it to the interview, I hope I can get offered the job. I know the people at my job will be shocked if I put in my two weeks notice because they are banking on me taking over when the lady I work with leaves. It is just so many little things at that job that seems like it gets bigger and bigger to where I get irritated all the time and I just don't want to be there anymore. I pretty much like the people at my job and I like the job I do but I just don't want to be there anymore. Hopefully things will work out to where I can be out of there by my goal time which is no later then the end of June.
